It is more that the RTS is generated as a part of the normal code
generation process, this is done by implementing as much as possible in
haskell itself, jhc has a very rich set of unboxed primitives, making it
as expressible as c-- for the most part, for the bits of C I do need, I
try to make them conditionally compilable, so parts that arn't used will
not be included. all in all, the overhead is ~= 1k or so. A side effect
is that jhc is very lightly coupled to any particular RTS, so
experimenting with alternate ones is pretty straigtforward.
