The poll() system call may return -1 with errno set to EAGAIN.  I have
two questions regarding this condition.

First, is there a kernel resource which has run dry which can be
increased by some tuning parameter to prevent this?

Second, how should software handle this condition?  For instance, can
the software depend on getting a SIGPOLL signal later if poll was unable
to tell the software what to examine in the first place?
