This uses the PAGESIZE constant from the unistd.h on POSIX. This should make the code more resilient to being compiled on platforms with different page sizes.

I know the build is actually free of STL linkage. However, snmalloc is not freestanding buildable because of the following: https://github.com/microsoft/snmalloc/blob/6af38acd94d401313b7237bb7c2df5e662e135cf/src/snmalloc/ds_core/redblacktree.h#L6 Could we include the `` header conditionally?

Also fixing the build with PAL::posix assuming the intent is to avoid using std namespace for max but rather using the in-house implementation.
Now BatchIt has landed in snmalloc, we should set up a release. I think it would be beneficial to have a few Markdown files explaining new features in this release....
Continuation of: https://github.com/microsoft/snmalloc/pull/771. I made a new PR since it was a somewhat different concept from the original. This seems to be a more correct way to cleanup at the...
