- Remove stale comment.
- In the last revision the code was changed to use maxfilesperproc rather than
the per-process file limit to restrict the size of the poll array. This
eliminates a significant source of process lock contention in multithreaded
programs and is cheaper. This had been committed with the wrong batch of
changes.
