I've just committed a fix to the tree which should *hopefully* fix the problem with the server locking up, when using Exec-Program-Wait.
If you're using Exec-Program-Wait, and are willing to test the CVS snapshot from tonight, please try it out, and report success/failure to the list. If this change doesn't solve the problem, then there's more work to do. If it DOES solve the problem, then it would help enormously to know that. Alan DeKok. - List info/subscribe/unsubscribe?
