I also see this with Safari 4.0.3 on Windows XP. I couldn't test with any newer WebKit version (Windows nightlies won't launch for me, and neither does a local debug build).

To clarify - I did see that load never stopped, and CPU usage was high. I didn't see a crash.

Hmmm... Can't reproduce with r49783 on Mac OS X.

Oops! Alexey reminded me that this is a Windows bug.
