Is there a page somewhere on how to program D without using
the GC?
The information is scattered.
How do I allocate / free structs / classes on the heap
manually?

Thanks.
I notice you avoid GC altogether in dplug. Whats the reason for
total avoidance as apposed to just avoiding it in the real time
code?
Not a lot of reason.
It's very recent work, I'm still struggling making threadpool
works.
- Reason #1 was that it gives a way to unload shared libraries on
OSX. This bug has been fixed in LDC but would require to make
druntime and phobos a shared library to ship. That makes releases
3x larger so I went with disabling the runtime instead (one month
of work and still going...).
- Reason #2 is that GC does use more memory. Next release of our
products use 2x fewer memory.
All in all it's _painful_ not to use the D runtime, suddenly you
can't use third-party code, and there is no performance
enhancement to expect apart from reduced memory usage.
Don't avoid the runtime on principles alone.
