I was aware of this, and I should write about it.

And because of this I wrote that it would be nice if it was easier :-)
I've bitten several times by the default values of RTS options,
especially the stack size limit (-K). But it was always easier to
set GHCRTS or use +RTS -RTS, so I never used the rts-hooks.

Do you think I could do this? I am not sure how difficult it would be.
