[issue15798] subprocess.Popen() fails if 0, 1 or 2 descriptor is closed

[Gregory P. Smith]

Gregory P. Smith added the comment:

F_DUPFD_CLOEXEC appears exclusive to modern Linux kernels.  Any idea how wide spread support for plain F_DUPFD is?  If that is "everywhere" the code I've just whipped up could lose a lot of loops...
