I thought about that for a while, but if you keep your classes/files
small, intra-unit parallelization gains are probably not worth the
time invested. Compiling multiple files is embarrassingly parallel.

MHO is that, though inter-unit optimizations can take much longer, the
benefits are worthwhile. Multiple threads/processes with a message
passing interface in between them would be a start, but compiling a
unix kernel that way would be tricky memory-wise. ;)
