History
Michael Lotz df7096a4aa * Added malloc_nogrow() function that does allocation without triggering or 
waiting for a heap grow.
* Use that nogrow version in the VM code to avoid a deadlock with the address
  space lock when a grow operation would try to create an area while a malloc
  happened from such a function in the VM.
* When waiting for a grow to happen, notify the waiting thread from the grower
  also if it failed to allocate a new heap. Otherwise a thread would just sit
  there and wait until another thread requested growing too and that one
  succeeded (or just forever in the worst case).
* Make the dedicated grow heap growable too. If the current grow heaps run low
  on memory it will instruct the grower to allocate a new grow heap. This
  reduces the likelyhood of running out of memory with no way to grow to a
  minimum. As the growing is done asynchronously it is still possible to
  happen, but it is highly unlikely as the grow heap is solely used to
  allocate memory in the process of creating new heap areas and it will even
  try using normal public memory if the dedicated memory has run out.
* Reduced the dedicated grow heap from 2 to 1MB. As it can now grow itself, it
  doesn't need to last so long.
* Extract heap creation into it's own function that does area creation and heap
  attach and use this function for growing normal and grow heaps.
