Hi --
I am not well-versed in Haskell-specific multi-threading, but usually there
is a better way to do what you want that does not involve killing threads
(which in most cases is bad idea.)
For example, using non-blocking IO and e.g. a synchronized condition
variable; hWaitForInput might work in your case, or something like the
following: http://hpaste.org/52742
Nevertheless, as a guess, I think you may want to try using closeFdWith,
perhaps combined with a call to threadWaitRead before actually calling
hGetLine. The wrinkle is that those operate on file descriptors instead of
handles, but there are fdToHandle/mkHandleFromFD to bridge the gap.
Hope that helps,
Alvaro

Hello,
The simplified problem:
There are two threads, one which is waits on input via hGetLine and another, which should terminate this thread or close this handle.
hClose as well as killThread doesn't seem to work, caused by the fact, that the thread is blocked until input is availiable.
Hopefully you have some solution how to kill the thread and/or close the handle and/or have some other idea to get the lined input in the other thread.
