[issue4216] subprocess.Popen hangs at communicate() when child exits

[Gabriel Genellina]

Gabriel Genellina <gagsl-py2 at yahoo.com.ar> added the comment:

I think communicate() works as documented now: reads stdout/stderr 
until EOF, *and* waits for subprocess to terminate.

You're asking for a different method, or perhaps an optional 
parameter "return_when_died" to communicate, so it returns as soon as 
the child process terminates (I don't like the parameter name...)

I think this is more a feature request than a crash, targeted to 
2.7/3.1 - 2.4 only gets security fixes anyway.
