How will that help?

For a small compile everything is quite likely to be dominated by I/O
performance. This is likely to be bad as I don't think we've found a way of
turning on interrupts on the Connect32 (I could be wrong on this). Polling
drivers are an absolute pain in OSes that do preemptive multitasking and there
isn't much we can do about this until we figure out how to enable interrupts on
the Connect32.
