[issue1495802] cygwin: popen3 lock up

[Charles-François Natali]

Charles-François Natali <neologix at free.fr> added the comment:

It's not a bug.
so.readlines reads the subprocess' stdout until EOF is encountered, but in the meantime, if it writes a lot to stderr, the corresponding pipe fills up, and the subprocess blocks on the write.
You should use Popen's communicate method.

Closing as invalid.
