rubygem-lockfile

Ruby library for creating NFS safe lockfiles

rlock creates NFS safe lockfiles. it can optionally run a program while holding the lock, ensuring lockfile removal on program exit. if a program is specified to be run rlock will spawn a background thread to kept the lockfile 'fresh' by touching it at a regular interval. in this way a lease is maintained on the lockfile and other processes attempting to obtain the lock can determine that it is in use.
