Not too likely. The hard part of implementing dtrace isn't porting over the program itself, it is the huge number of OS kernel hooks required to instrument. Tho

Not too likely. The hard part of implementing dtrace isn't porting over the program itself, it is the huge number of OS kernel hooks required to instrument. Those are unlikely to be back-ported.
