Running dmd with huge page backed malloc resulted in about 10%
faster compilations.
This looks very promising though other tests with some D GC
microbenchmarks did not benefit from huge pages.

I'm interested in adding a runtime parameter that would advise
the GC to preferably use huge pages as backing memory.
There are a number of other interesting runtime parameters, like
max heap size, GC grow policies, turning on statistics, so I
wonders how to make them available.
Java seems to use -XX:+UseLargePages and -Xmx for the maximum
heap size.
GHC uses a nice scheme where runtime parameters passed via
command line are embraced by +RTS arg1 arg2 -RTS. They also
require to link-in support for this.

Any good ideas for druntime?
