No. Either you catch exceptions resulting from a lack of memory and
recover, and then you have the same checking as before, except that
the check happens atomically (by the OS: you ask for more memory and
if there is no more memory, you get an exception).
Another possibility to set the global system unit variable
ReturnNilIfGrowHeapFails to true, and then you can check after each
allocation whether the resulting pointer is nil (if so, not enough
memory was available) or not.
