This change significantly improves NFS server scalability, since it had

This code is more optimized for relatively small number of mount points.
On systems with hundreds of active mount points this simple cache may have

Further reduce diffs with OpenBSD's arc4random. The main functional
change here is to ensure that when a process forks after arc4random
is seeded, the parent and child don't observe the same random sequence.
OpenBSD's fix introduces some additional overhead in the form of a
getpid() call.
The only significant remaining difference between our arc4random and
OpenBSD's is in how we seed the generator in arc4_stir().
