Lasso 8.5 Zombie Child Thread Killer

This routine kills zombie child Lasso sites. The rouge child site tend to randomly appear after running Lasso 8.5 heavily after a few days - they hog unncessary memory.

Warning - Requires RD_lassoService_pid

This script can be run periodically to cull any rouge zombie Lasso sites - tested on OSX. It requires RD_lassoService_pid to be installed within LassoStartup for each LassoSite.

1. http://tagswap.net/RD_lassoService_pid
2. Running once per day early morning should suffice.
3. Remove back slashes from code where noted

Use at your own risk...
