True, if you have more threads running than actual processors, you
will share a heap across multiple threads, not sure what you mean
with "synchronize their allocations" though.

If multiple user threads can share a single heap then they cannot
allocate from it independently: their allocations must be
synchronized using a lock.
But Ben Voigt said that no locks were used during allocation.


"object allocation" is nothing more than bumping a pointer in an
atomic operation.

Right. Because the Gen0/Gen1/Gen2 heaps... aren't. They are really stacks.


Yep the back-end is, but with a complex front-end.
