For one, not all jemalloc users are going to have the problem, which is
limited to some APIs.
Also, AIUI, the current jemalloc code does the right thing for the
ozone_size, which is not the case in the old jemalloc fork we use in
Firefox, so depending on what is done with the result of ozone_size,
it might be okay.
