SVN rev 195259 on 2009-07-01 20:43:46Z by jeff
- Use fd_lastfile + 1 as the upper bound on nd. This is more correct than
using the size of the descriptor array.
- A lock is not needed to fetch fd_lastfile. The results are stale the
instant it is dropped.
- Use a private mutex pool for select since the pool mutex is not used
as a leaf.
- Fetch the si_mtx pointer first before resorting to hashing to compute
the mutex address.
