The problem is not in hooks/etc.
The problem is that interpreter MUST TEST EVERY operation result that
may fail on memory allocation. And it MUST return an error to all higher
levels, closing and freeing all allocated resources on the back way.
The existent interpreters either do not test result in most cases (perl),
or simply exit(), or in best case they throw exception. Exceptions are easy
way to program (you not need to test most operations) and cheap way to test
results (for the same reason), but they may lead to socket/file descriptor/etc
