	Lovely ! :-) so we halving(?) the number of processes being spawned
halves the time ?

	I guess the other big win there to get the time down to seconds would
be to get idlc/'s idlcpp to compile lots of these IDL files at once.
That looks like something that idlc/source/idlcmain.cxx either already
does, or could trivially be adapted to (with a rather easy-to-verify
"did it work" mode by diffing the generated .hpp/.hdl files I guess).
That is assuming that some large chunk of the overhead on windows comes
from several thousand invocations of the same small tool :-)

	Would that interest you Matus ? or should I file an easy hack ?

	Anyhow - nice work, and lovely speedup :-)

	All the best,
