On my machine, I/O from gas and gcc is compute bound. I expect it's
the same on most systems. Modern caching techniques are pretty good,
and there aren't really many programs which have a working set of more
than 100Mb while compiling (and then it's usually because GCC is being
a glutton, not because of the size of the sources and objects).
