I am running ghc 6.4.2 on a Win32 machine. I'm using hs-plugins in one thread and a simple getLine loop in another. It appears that getLine blocks the hs-plugins thread on Win32 (this has been verified to work fine on freeBSD). I've tried various combinations of -threaded flag and forkIO/forkOS and always get the undesireable result.
_may be_ it is one more consequence of lack of IO manager in windows/threaded RTS ( http://hackage.haskell.org/trac/ghc/ticket/637 )
Oh, that's almost certainly it. Bulat++ It's blocking on the foreign call (into the linker), since there's no IO manager thread, I think.
try _without_ -threaded. if it don't work, you can try my I/O library: http://haskell.org/haskellwiki/Library/Streams
use 'vGetLine fdStdIn' in order to read lines. you should strip chr(13) at line-end by yourself because my lib don't implements CR+LF->LF conversion
feel free to ask me more, i'm speaking russian ;)
