           Summary: NRWT should not take memory used as disk cache into
                    account when deciding how many processes to launch
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: timothy_horton at apple.com
                CC: jberlin at webkit.org, dpranke at chromium.org


On OS X:

> run-webkit-tests fast
This machine could support 24 child processes, but only has enough memory for 13.
> purge
> run-webkit-tests fast
This machine could support 24 child processes, but only has enough memory for 23.

"purge" empties purgeable disk cache; this memory shouldn't be included when measuring how many children NRWT can make, as it will quickly evict itself if and when DRT/WKTR want it.

(please don't solve this by purging my disk cache :D)
