https://bugs.webkit.org/show_bug.cgi?id=29256

           Summary: Use MemoryManager to gather platform-specific low
                    level memory requests
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Platform
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: yong.li at torchmobile.com


There are a few places in JSC where low-level memory allocation is required:

1. Collector.cpp: allocating 256k (previously 64k) JS blocks.
2. RegisterFile.h, cpp: reserving a big chunk of virtual memory and committing
gradually.
3. MarkStack*.cpp: allocating/increasing aligned memory.
.....

Introducing an abstract layer MemoryManager allows better low-level memory
management and customized implementations.

Patch is coming soon.
