I am trying a few things on Squeak 5.0.  In earlier versions there was
AndreasSystemProfier (formerly known as QSystemProfier) and had a
method called spyOnWorldFor:, which was quite useful.  I just loaded
AndreasProfier-eem.11.mcz and tried it but it crashed the 5.0 all in
one VM on Mac OS 10.10.

Is this a known issue?  Is there an alternative to it?
