Code Issues Releases Activity

* Add support for hw.physmem and hw.usermem sysctls (this allows sysinstall

Browse Source 
to calculate a reasonable size for the swap partition).
* Fix a typo in remrq() where a process with idle priority would not be
  correctly removed from the relavent queue.  Note that realtime and idle
  priorities are still not supported since the assembler code in
  cpu_switch() does not check the realtime and idle queues.
