The poll system call is documented to have an error return of EAGAIN
if an internal data structure allocation fails.  EAGAIN traditionally
is returned on fork(2) failing for a 'temporary' condition such as too
many processes.

What resource does poll need and can you increase this resource on
typical binary configurable kernels?

I've seen programs enter what seems to be infinite loops calling
poll which always returns EAGAIN.  It would be nice to have some ideas
to clear up this problem.
