Might be of use to someone, but I was looking for ways to speed up
dmd's albeit already fast compilation times.
Just by dropping in jemalloc in place of glibc's malloc via LD_PRELOAD
on my linux machine I saw a 10-15% drop in compilation times across
the board. Not sure if this is common knowledge or not.
Might be interesting to try some other implementations, too? TCMalloc[0]
and nedmalloc[1] at least have permissive licenses. (Hoard[2] and
Lockless[3] also seem interesting, but are GPL or worse.)

Definitely measurements should help. From the many measurements we've
run at Facebook, jemalloc would be overall a good bet. Also I work with
Jason Evans so if there are issues we want improved I might ask him :o).
