Try turning on the profiler.  Quothe the control panel:

  To enable profiling, restart the Zope process with the environment
  variable PROFILE_PUBLISHER defined. The value of this variable should be
  the full system path to a file that will be used to dump a profile report
  when the process restarts or exits.

And kill the process.  Maybe this will create a profile report that tells
you where it's spinning.

Are you sure your waiting long enough?  If you have a large Data.fs and you
just move it over to a new install, Zope needs to take some time to build
the initial database index file.
