You often see people using the profiler for benchmarking instead of
profiling.  I suggest adding a note that explains that the profiler
modules are designed to provide an execution profile for a given
program, not for benchmarking different libraries or, even worse,
benchmarking Python code against C libraries.  Point people to the
"timeit" module if they want resonably accurate results.

(and yes, it would be nice if the copyright text on the page

http://docs.python.org/dev/library/profile.html

was moved to the bottom of the page.  If necessary, add something like
"This description of the profile module is Copyright © 1994, by InfoSeek
Corporation, all rights reserved.  Full copyright message below" at the
top.)
