Sounds like the best environment for a multitasking/multiuser operation
system. :^)

Serious, I think it is time to make the change. Most systems have enough
memory today (but unixes can not handle it - oops :-). Disk I/O is a real
neck of a bottle in multiuser systems and therefore "-pipe" makes cc faster.
What's about the idea to make cc a little bit more intelligent and let it
decide alone if it should use pipes instead of disk I/O or not depending
on the remaining physical memory? Some statistics about the static and
dynamic memory usage calculated by the kernel would be very useful.
