Comment (by tomekz):
Ha! I've just found these words from Simon Marlow, in glasgow-haskell-
users thread "ghci and ghc -threaded broken with pipes & forking" from
March 2007:
In fact you should think of the non-threaded RTS as deprecated. It isn't
Haskell'-compliant, for one thing (assuming that Haskell' will probably
require non-blocking foreign calls).
I'm hesitant to actually deprecate it, for a few reasons: the threaded
RTS is so much more complicated, it might have some adverse performance
impliciations, and there are still people who want to run everything in a
single OS thread, for whatever reason. But having multiple variants of the
RTS is a maintenance and testing headache.
One more reason to deprecate the non-threaded RTS, or at least to pick the
threaded by default. I'll add something to that discussion.
