[Mono-list] exceptions are not thrown from ThreadPool'ed thread objects?

[Mariano Alarcon]

I see the same results (exception not thrown) in my gentoo with mono 
1.0. But when I take the mcs binary and run it on my winxp with ms.net 
1.1 the exception is caught by the main thread. I don't know what the 
correct behavior should be, but there is certainly something different 
between the two implementations.
