Description

radostool still seems to be hanging from time to time on shutdown.
Sending a signal resolves the issue.

For example, doing CTRL-Z followed by fg. (i.e. sending SIGSTOP followed by SIGCONT).

It's probably a SafeTimer thing. I think I have a fix.

Here's a backtrace from a hung radostool:
