[Haskell-cafe] STM and `orElse` on a few thousand TMVars

[Joel Reymont]

I'm trying to implement a better waitForChildren from the docs for  
Control.Concurrent.

I would like to know when all the children exit, basically, and I  
thought it would be neat to try to do that with STM.

Is there an advantage to STM here?

	Thanks, Joel
