Summary: Segfault on MVar-abuse

Initial Comment:
The attached program segfaults using 6.4 on FreeBSD at the 2nd 
takeMVar. Sorry, no HEAD to test with atm (I understand that the 
program might be strechting the limits a bit ;).
Other interesting effects can be observer, e.g. a rather unexpected 
"threads blocked indefinetely" when commenting out both lines (1) & 
(2) OR having both lines activated.
