I think its reasonable to merge this with WTF/wtf/linux/MemoryFootprintLinux.cpp
and share the code.

For example, getCurrentMemoryUsage() can be implemented as returning ProcessMemoryStatus.resident after calling currentProcessMemoryStatus(ProcessMemoryStatus)


Adding resetPeak() to MemoryFootprintLinux.cpp is also reasonable.
