GREENMAN BUGFIX KIT
1. Buffers were being immediately aged after read, greatly reducing
file system performance.
2. The file system buffer cache hash calculation resulted in hash
collision occuring 100% of the time.
3. File system buffers were allocated twice. They were also deallocated
twice, so there was not a memory leak, but freebufspace was incorrect
and too much memory was being used.
4. Unnecessary call to swapout_threads in the vm system.
