- in addition to a memory_limit configuration directive, there could
be a "memory_limit_grace" configuration directive. This gets stored in
the struct _zend_mm_heap, along with the limit.
That could be a problem because it's very hard to know exact memory requirements for PHP code for most people not intimately knowing the engine internals, and also recovering from failed allocation usually is not simple since management structures could be in half-done state. So writing useful handler for such an error would be rather hard to do.
Having said that, what exactly would you plan to do in this error handler?
