--enable-zsh-mem should turn on the internal malloc, see line 1026 of
mem.c.  However, if you didn't relink separately-compiled modules,
they might still link at runtime to the system malloc.

} I'm writing a module that needs thread safe memory allocation.

This sounds pretty dangerous, as the rest of zsh (signal handling in
particular, update of the environment on e.g. "export", etc.) is not
going to be thread-safe.
