           Summary: Use the Windows thread pool instead of an extra thread
                    for FastMalloc scavenging
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Keywords: NeedsRadar, PlatformOnly
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: aroben at apple.com


FastMalloc creates a background thread for scavenging free memory.  The thread wakes up every five seconds, scavenges some free memory, then goes back to sleep.  It may be more efficient to schedule this small amount of work on the Windows thread pool, perhaps using a timer-queue timer.  It'd certainly be nicer than having a new thread run for the lifetime of the application just because JavaScriptCore was touched.
