Question: how can I do that? Use another threaded class? Is there

First of all, thanks for answer!
What OS? Does this have to be OS-independant?
Err, sorry -- this is Linux/UNIX only.
Are you using more then
one transport/SSLClient in your process and you want to just kill one
(and any of its child threads), or are you doing one per process?
I'm using multiple threads myself, one per IP basically, which in turn
call paramiko calls, which itself is threaded.
If you want to terminate -all- threads your process is running in a
given timeframe, using a SIGALRM in the signal module will do it, I
believe-- provided you don't need to support windows.
Thanks, that's still useful! Although...
1. if I don't install signal handler for SIGALRM I get this printed on
the console at the end of execution:
Alarm clock
Although it does seem to close cleanly.
Is there any way to suppress this message?
2. If I do install signal handler for SIGALRM, I'm back at square one:
Exception in thread Thread-25 (most likely raised during interpreter
shutdown):

This happens even though I surround "connect" (line 1006) with catching
all Exceptions:
try:
self.trans.connect(hostkey=None, username=self.username, pkey = pkey)
except Exception, e:
self.conerror = str(e)
I had a contextlib
manager do that for awhile. If you only want to terminate one (and its
child-threads)... you're out of luck, I think. The only way to terminate
a thread in Python is with conditions/events/whatever and the thread
cooperating and exiting on its own.
I will probably have to get the library author look at this.
