| 05:46 | Fixed actual problem with interruptions (which was really unrelated) -- Tcl notifier thread is terminated on fork() called by fuse_main(), since we create a Tcl interpreter for testing before calling fuse_main() the notifier dies and is not restarted. We now terminate it before fork(). check-in: 0819a7a89c user: rkeene tags: trunk | |
