I think the idea was to call the C lib fcn and then do some housekeeping
before returning, eg (in pseudo code): errno_table[thread] = errno
You'd have to disable the thread scheduler in order to ensure that
errno wasn't changed by some other thread between the setting and
reading. Not pretty. Better to avoid the situation completely if
possible.
