Hi,
	As a data point, I do make -j{2,4} builds on powerpc G4, G5, and
Intel Core Duo iMac every day with no problems.  I do get occasional
fork/vfork errors failing to launch too many processes, but that's not
XCode's/make's problem.  [Yes, there are people on this list who've never
opened XCode.  :P Call me archaic.] One final tip regarding mdimport: I
always disable spotlight on my build directories (Preferences:Spotlight),
which are always separate from by source directories (VPATH building).
This way spotlight can happily index the source tree and not bother with
built objects.
