Could you summarize the advantages (or need) of the threaded RTS?

It doesn't work under solaris and under linux [1] my nightly compilation
jobs are "killed" every tuesday morning (!) for some reason that i
cannot reproduce. I suspect the threaded RTS and heavy load. I had no
such problems with ghc-6.4.1 before.

As a friend of pure functions I hate such a non-deterministic behaviour
of a (mere) compiler.

Cheers Christian
