Thanks Alexey for your attentiveness to the matter.  I can confirm that the memory growth is continual until the crash, according to the Windows process monitor.  I figured the issue was memory related, so I apologize for not including this tidbit in the bug report.

The only crash report I can provide right now is that from the Windows crash dialog:

Problem signature:
  Problem Event Name:    APPCRASH
  Application Name:    Safari.exe
  Application Version:    5.31.22.7
  Application Timestamp:    4b8f94fa

  Additional Information 1:    fd00
  Additional Information 2:    ea6f5fe8924aaa756324d57f87834160
  Additional Information 3:    fd00
  Additional Information 4:    ea6f5fe8924aaa756324d57f87834160

It's outside of my scoped effort on this bug to reconfigure my workstation and reboot the machine.  Sorry.  I hope the above helps.  If you'd like me to provide the dissassembly where the crash happens, I am willing to do that.  I did not build Webkit from source for this bug.

> I'm seeing the same memory growth with shipping Safari 4.0.5 on Mac OS X as I do with r60082 nightly.

Yes, I concur.  In fact, I first observed the behavior in the shipping Mobile Safari on the iPad, and have since observed it in all Webkit based browsers I use -- Chrome, and Desktop Safari).  The issue is least pronounced on Desktop Safari, but as you note it is still present.

Thanks again for the prompt attention.
