The PyPI pexpect.spawn API is incompatible with multithreaded code thanks to its dependency on pty.fork() and running non async signal safe code between fork() and exec(). https://github.com/pexpect/ptyprocess/issues/43 https://github.com/pexpect/pexpect/issues/369 If subprocess supported pty.fork() and pexpect.pty_spawn.spawn like actions, pexpect could use that by default instead of the threading incompatible pty.fork(). (this is a brainstorm, see what the pexpect maintainers want in the above github issues)
