[issue25960] Popen.wait() hangs when called from a signal handler when os.waitpid() does not

[Gregory P. Smith]

Gregory P. Smith <greg at krypto.org> added the comment:

yes, Popen's use of a lock since that change means that Popen.wait() cannot be called in an asynchronous context where its own execution could be blocking the execution of code that would unlock the lock.

at this point we should probably just document that.
