It looks useless nowadays, because operator new cannot throw
MEMORY_LIMIT_EXCEEDED today, and so any code that works on Exception is
likely safe.

In case of memory allocation had been failed, it should not be take into
account anywhere, otherwise it will report incorrect memory usage for
query and in logs.
I found this while was digging into OOM in stress tests, and saw memory
allocations that had been significantly greater the memory limit (even
with overcommit).
