 The integer must be a decimal number in the range [0,4294967295].  Specifying
 the value 0 will disable hash randomization.
+.IP PYTHONMALLOC
+Set the Python memory allocators and/or install debug hooks.
+The available memory allocators are "malloc" and "pymalloc".
+The available debug hooks are "debug","malloc_debug",
+and "pymalloc_debug".
+
+When Python is compiled in release mode, the default is "pymalloc".
+When compiled in debug mode, the default is "pymalloc_debug" and
+the debug hooks are used automatically.
+
+If Python is configured without "pymalloc" support, "pymalloc" and
+"pymalloc_debug" are not available, the default is "malloc" in release
+mode and "malloc_debug" in debug mode.
+
+.IP PYTHONMALLOCSTATS
+If set to a non-empty string, Python will print statistics of the
+pymalloc memory allocator every time a new pymalloc object arena
+is created, and on shutdown.
+
+This variable is ignored if the PYTHONMALLOC environment variable
+$PYTHONMALLOC is used to force the "malloc()" allocator
+of the C library, or if Python is configured without pymalloc support.
+.IP PYTHONASYNCIODEBUG
+If this environment variable is set to a non-empty string,
+enable the debug mode of the asyncio module.
+.IP PYTHONTRACEMALLOC
+If this environment variable is set to a non-empty string,
+start tracing Python memory allocations using the tracemalloc
+module. The value of the variable is the maximum number of frames
+stored in a traceback of a trace. For example,
+.IB PYTHONTRACEMALLOC=1
+stores only the most recent frame. See the documentation
+.IR tracemalloc.start()
+ for more information.
+.IP PYTHONFAULTHANDLER
+If this environment variable is set to a non-empty string,
+.IR faulthandler.enable()
+is called at startup: install a handler
+for SIGSEGV, SIGFPE, SIGABRT, SIGBUS and SIGILL signals to
+dump the Python traceback.
+
+This is equivalent to the -X "faulthandler" option.
+.IP PYTHONEXECUTABLE
+If this environment variable is set,
+.IB sys.argv[0]
+will be set to its value instead of the value got through
+the C runtime. Only works on Mac OS X.
+.IP PYTHONUSERBASE
+Defines the user base directory, which is used to compute
+the path of the user site-packages directory and Distutils
+installation paths for "python setup.py install --user".
+
+.SH DEBUG-MODE VARIABLES
+
+Setting these variables only has an effect in a debug build
+of Python, that is, if Python was configured with the
+\fB\--with-pydebug\fP build option.
+
+.IP PYTHONTHREADDEBUG
+If set, Python will print threading debug info.
+
+.IP PYTHONDUMPREFS
+If set, Python will dump objects and reference counts still
+alive after shutting down the interpreter.
