Thanks. Works on my RHEL6 box too, so pushed.
This certainly explains the "could not resize ...: Success" oddity
we see in the buildfarm. It's not so clear why those critters are
failing in the first place. I hope that what is happening is that
they are getting EINTR results and failing to retry. (Although
my RHEL6 man page doesn't mention EINTR as a possible failure,
I see that's been corrected in later editions.) If not, we should
at least get a better fix on the nature of the failure with this
patch. Awaiting buildfarm results ...
regards, tom lane
