* Workaround for processExecAsyncTimed bug
When a process, created with the function processExecAsyncTimed,
stops it makes WxHaskell die with "Prelude.chr bad argument". The
problem is reported elsewhere
http://sourceforge.net/mailarchive/message.php?msg_id=54647.129.16.31.149.1111686341.squirrel%40webmail.chalmers.se
and here
http://www.mail-archive.com/wxhaskell-users@lists.sourceforge.net/msg00267.html
.
This patch does not solve the underlying problem, as it is still unknown, but
do create a workaround.
The bug has only been seen on Linux systems.
