RE: [Haskell-cafe] killing a running thread interactively

If you can get ThreadIds for the threads, yes. GHCi doesn't (currently) create a new thread for each expression evaluation, so attempting to kill that thread might kill your GHCi session (it shouldn't but that's another story). Cheers, Simon
Is the general pattern to write all threadIds to a file, and then have a separate function that takes the file and kills them? Or is there something more clever? -Alex- On Wed, 21 Sep 2005, Simon Marlow wrote:

More particularly, is there a getAllThreadIds function somewhere? -Ale- On Wed, 21 Sep 2005, S. Alexander Jacobson wrote:
