it's super easy to change memory allocator for any process using LD_PRELOAD either way
yah -- Rust leans on jemalloc
I'd expect it to stop being the default on all platforms in due time. jemalloc is way too buggy, and seemingly getting buggier
also a big culprit in bloating up binaries, which is an annoying thing to have to explain.
for embedded libs "system allocator" is usually a better choice.
in Ruby it is a compilation flag or on-demand, not default :( https://bugs.ruby-lang.org/issues/9113
i've got a case when jemalloc were slower than glibc malloc : alloc many kbytes in many threads and free them in main thread.
