I haven't been able to get at the cause for the freezes, yet, for 
impara's squeaksource installation (3.7 image, stock Linux 3.7-7 VM).

We guess it's related to a networking problem in the VM. Because when it 
  freezes, I just need to VNC into the machine, move the mouse pointer, 
and it comes alive again.

The freezes regularly occur under heavy load, that is, multiple package 
uploads causing a save of the in-memory meta data. My gut feeling is 
this is related to async i/o, which somehow blocks, and is woken up 
again when an X11 network packet arrives.

OTOH, I haven't heard of similar reports for other seaside apps. OTTH, 
the usage pattern in squeaksource might be unique, nobody else is 
serializing a multi-megabyte object network for each modification.
