[issue15896] Sporadic EINVAL in nonblocking pipe os.read when forked child fails on Mac OS

Although this issue was initially filed as "Sporadic EINVAL in nonblocking pipe os.read when forked child fails on Mac OS", the subsequent investigation revealed that this has nothing to do with a forked child failing.  Rather, it's a bug in the read() syscall on Mac OS X.  What would be a more appropriate place to work around this read() syscall bug than os.read?
