It is possible to deadlock EDB by attaching the it's parent console. I've only 
observed this with konsole from KDE.

Seems to be resolved on my current development machine (which is running kde 
3.5.8)

OK, seems to still be reproducible. I imagine it has to do with EDB outputting 
to the console it is debugging. Perhaps we should somehow forbid this. I 
suppose the easiest solution would be to have a custom logging window separate 
from stdout.

Fixed in the SVN. You may not attach to a process which is a parent of the EDB 
process. This includes grandparents, great grandparents, etc.
