I don't have support for building on multiple cores, but trying it on 
visuald itself (48 files) yields

- combined compilation    6s
- single file compilation 1min4s

You'd need a lot of cores to be better off with single file compilation.

These are only the plugin files, not anything in the used libraries 
(about 300 more files). Using dmd compiled with dmc instead of cl makes 
these times 17s and 1min39s respectively)

Almost any change causes a lot of files to be rebuilt (just tried one, 
took 49s to build).
