Strange. It would help if you could show more of of your code.
I am attaching a sample program which shows this. I am using 6.12.3 on both Linux and Mac OS X. And I run this program with runhaskell Test.hs. Without "throwIO ThreadKilled" it outputs:
Test.hs: MyTerminateException MVar was successfully taken
With "throwIO ThreadKilled" is as expected, just:
MVar was successfully taken
So MVar is filled. What means that thread gets exception after that. But there is nothing after that. ;-) (At least nothing visible.)
This is really interesting. Presumably what happens is that an exception is indeed thrown and then raised in the thread after the final action. Now if you synchronously throw an exception at the end it looks like it's raised before the asynchronous exception is raised. Hopefully one of the GHC devs (probably Simon Marlow) can confirm this behavior and shed some more light on it. Bas
