Silly or not, if I compile with -threaded, I always link in the one-liner C file:

char *ghc_rts_opts = "-N2";

so I don't have to remember at runtime whether it should run with 2 cores or not. This just changes the default to 2 cores, so I am still free to run on only one core with the runtime flags +RTS -N1, though I rarely need to.

Ah... you learn something useful every day! I was going to ask on IRC whether there's any way to do this - but now I don't need to bother. :-)
