Zygo Blaxell 86afa69cd1 cache: release lock before clearing ...

Clearing the FD cache could trigger a lot of inode evicts in the kernel,
which will block the cache entry destructors called by map::clear().
This prevents any cache lookups or new file opens while it happens.

Move the map to an auto variable and destroy it after releasing the
mutex lock.  This probably has the same net result (all the bees threads
will be blocked in the kernel instead of on a bees mutex), but at least
the problem is outside of userspace now.
