There's a whole section in the glibc manual on "Memory Allocation
Tunables", which is the "new" way to do this.
"man mallopt" is the other way.
Using these you could, for example, disable the tcache and fastbins
completely and see how that works for you. Or limit the number of
arenas. Or let smaller allocations go directly to mmap().
There are some environment variables which affect malloc, but we're
trying to get rid of those.
Maybe in ten or twenty years we'll come up with some better way, but
that's the future's problem ;-)
