[issue15918] subprocess.Popen reads errpipe_read incorrectly, can result in short read

[Gregory P. Smith]

Gregory P. Smith added the comment:

Yeah, sounds like _eintr_retry_call alone isn't appropriate here in 2.7.
I'll fix it.

In practice I doubt this matters much as this error string is likely to be
less than one page (depends on pathnames involved) but it is still
technically incorrect as written.
