eval_thunk_selector: strange selectee 29

[Josef Svenningsson]

I can confirm that this happens on my solaris machine as well. Moreover it
crashes my computer! I have seen the same crash when working with the ffi
on solaris but haven't been able to reproduce it. What happens is this:
In the window I'm running ghci/my ffi application gets filled with
prompts. I'm guessing something has started forking like crazy. Anyway
this eats up all the computer resources and all I can do is restart the
computer.

It would be Very Nice if you could fix the crashing bug as this sometimes
crashes programs running for example wxHaskell. I get very uneasy as soon
as I start to program with the ffi.

Cheers,

	/Josef
