  I don't think in the Gnash case allocating from multiple threads
concurrently would buy much, as Gnash is not heavily threaded. The main
thing Gnash takes advantage of with jemalloc is separate memory pools
for each core of the CPU, which does make a difference. Along with that,
jemalloc also works better for all little allocations both C++ and
ActionScript use, than the system malloc.
