It isn't obvious how  to get the info so as to check for this error.
I kept running into this a year or two back, when prototyping several
some web apps (up tens of thousands of sockets simultaneously open).
I've since mainatiend a hack to procfs whichs appends the per-process
current open file count to the end of /proc/<pid>/status.

I still dont know of any better way to grab this info for an arbitrary
process.
