Description

I'm seeing fantastic performance with snmalloc in a resource constrained environment.

MiMalloc has MIMALLOC_RESERVE_OS_MEMORY and MIMALLOC_LIMIT_OS_ALLOC. Is there any equivalent for snmalloc?
I wan't to improve the startup of my program that i know upfront will allocate a lot of memory. But I also want to limit request anymore memory from the OS simlar to MIMALLOC_LIMIT_OS_ALLOC

Thank you!

Research direction

No files, tests, or entry points are named. Start by locating snmalloc's existing OS-memory reservation and allocation paths, then determine whether equivalents to MiMalloc's MIMALLOC_RESERVE_OS_MEMORY and MIMALLOC_LIMIT_OS_ALLOC are feasible. Done means a clearly specified and tested way to reserve memory at startup and limit later OS requests.
