No that has to be solved by a bigger granularity (compiling more units in
one go).  That avoids ppu reloading and limits directory searching (there is
a cache iirc) freeing up more bandwidth for source loading.

Not only compiling goes in paralel, I assume one could also load a ppu in
parallel? (and so parallelize the blocking time of the disk I/O and the
parsing of the .ppu contents.
