Arguments: sharable-lock &optional clean-p
Return the number of shared users locking a sharable-lock at some instant.
The clean-p has effect only
to sharable-lock instances
created with the auto-unlock-p to
make-sharable-lock specified
true (the default value is nil). In that
case, when the clean-p argument is
non-nil, the current owners of the lock are
scanned to remove any dead processes associated with the lock. The
returned count is the number of live processes associated with the
lock.
Note that this value may be obsolete and incorrect as soon as it is returned.
