Some software may require epoll.  Epoll seems to be more efficient 
than other Linux API alternatives given many open file descriptors. 
It is unfortunate that some software will enable use of a feature 
because its configure script detects that it exists.  Usually it is 
possible to force that a feature will not be used (e.g. by providing a 
cache value which says it is not available) when running a configure 
script.

The only real solution is to make sure that applications are using the 
most appropriate APIs under Illumos given their actual requirements.
