Re: [rvm-core] Renaming/aligning methods in org.mmtk.vm.Memory with Harmony?

Hi,

I'm interested in the interface to underlying OS operations used by MMTk:

dzmmap - demand zero mmap
mprotect - remove read/write protections to a region of memory
munprotect - allow read/write access to a region of memory

the equivalent Harmony interfaces are:

reserve - reserve a region of virtual memory for use
commit - allow access in a region previously reserved
uncommit - remove access to a region

for completeness there is unreserve (but MMTk has no munmap).

MMTk's dzmmap is equivalent to a reserve & commit, mprotect to uncommit, munprotect to commit. The Harmony interface more directly maps to that of Windows. It would make sense to me to push the Harmony naming convention through the RVM interface into MMTk's. I will provide a patch if other people agree.
