[issue12493] subprocess: Popen.communicate() doesn't handle EINTR in some cases

[Charles-François Natali]

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

Out of curiosity, how could SIGALRM be missing on a Unix system?
Maybe you mean something like
@unittest.skipUnless(hasattr(errno, EINTR),
                     "Requires errno.EINTR")
