safe values for the most commonly used modern architectures, there is a
wrinkle related to GNU libc (glibc) that may impact your choice of

https://sourceware.org/bugzilla/show_bug.cgi?id=206 . Unlike glibc,
jemalloc does follow the C standard by default (caveat: jemalloc
technically cheats if --with-lg-tiny-min is smaller than --with-lg-quantum),
but the fact that Linux systems already work around this allocator
noncompliance means that it is generally safe in practice to let jemalloc's
minimum alignment follow glibc's lead. If you specify --with-lg-quantum=3
during configuration, jemalloc will provide additional size classes that
are not 16-byte-aligned (24, 40, and 56, assuming
