The actual implementation of the phobos GC is triggered every time you
allocate new memory. This happens if you call 'new', increase the size
of an array, use '~' or use code which does this. If your thread is only
a little piece of code, you can perhaps write it, not using any allocation.

Interrupting the GC is possible, but it is a risk. You must be sure not
to manipulate memory in a way that affects the GC. (No allocations, no
moving of references ) If you are sure it doesn't you need a way to
reactivate your thread. An OS timer? The GC uses the Thread.pauseAll.
You can use resume or just run in the OS callback?
