	Are you certain lharc doesn't conflict with itself?  A number of
ported utilities are known to assume that only one copy of their program is
running (or running in a given directory).  Someone here has indicated to
me that lharc probably has this problem.

	The FS is quite reliable against large numbers of simultaneous
operations.  Unlike OFS, even re-use of the blocks of deleted files in a
directory while it's currently exnexting over them will not hurt FFS (the
classic design problem with ExNext).
