dmd's albeit already fast compilation times.
Just by dropping in jemalloc in place of glibc's malloc via

board. Not sure if this is common knowledge or not.

I thought dmd used a bump-the-pointer approach, since it
almost never
frees memory?
it not frees, but it still does alot of `new`. seems that
jmalloc is
better at it.

Looks like it only does that for C++ `new`.
