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.

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.
