## DESCRIPTION:
## This test creates 20 files (0 thru 19) and then shuffles them around,
## deletes, and recreates them as fast as possible.  This is all done in
## an effort to test for race conditions in the filesystem code. This test
## runs until killed or Ctrl-C'd.  It is suggested that it run overnight
## with preempt turned on to make the system more sensitive to race
## conditions.
