If by interactively you mean with csi: nope; it's in the middle of a
very complex system with thousands of lines of code in at least 4
languages. :-)
Oh, great! ;-)
Do you use with-exception-handler a lot? It has some subtle semantic
issues (handle.-exceptions is better, since an exception thrown in the
handler proc passed to with-exception-handler results in undefined
behaviour).
Does the process-wait inside an exception-handler work when run stand-alone
(without the rest of the code)?
Can you test whether the process is still alive, before doing the test
(perhaps by checking the /proc directory or through some other hacks)?
cheers,
