Softlock does weak, transient locking. This is useful to slow down a
deluge of events that can overwhelm hardware or software systems.
Locks are only good for one second, just enough time to spread events
out.
On NFS the Unix file locking mechanism works well but lock handling on
the filers can be overwhelmed by many locks occuring quickly. Jobs
that must use NFS file locks can use softlock to minimize the rate
that the file locks are created, preventing the NFS filer from being
swamped.
Environment variables:
SOFTLOCK_DEBUG_MODE - if defined enable some messages
WARNING: the file <lockfile>.softlock will be overwritten and removed by softlock!
