Parsing the file with DMD 2.058, with the GC disabled during
the LoadFile call, takes ~2.2 seconds.
For comparison, MSXML6 takes 1.6 seconds to load the same file.
Not too much time ago Python devs have added an heuristic to
the Python GC (that is a reference counter + cycle breaker), it
"switches off" if it detects the program is allocating many
items in a short time. Is it possible to add something similar
to the D GC?

I actually tried to add something like this a while back but I
couldn't find a heuristic that worked reasonably well. The idea
was just to create a timeout where the GC can't run for x
milliseconds after it just ran.
