That question has been asked by me :)  By inhumane and barbaric
experiments I found that backend successfully rolls back
transactions from dead clients. The only problem is that if
there was a process of creating new tables (or other stuff
like that), there remains a corpse of that semi-created table.
But someone said this problem should be addressed, or am I
mistaken? :)

Roberto has already reproduced two of three of my Big Questions:
speed of joins and sudden client death. :)  The third question
should be: what do I do with transaction deadlock, since there
is no lock wait timeouts?

Server should abort one of transaction to resolve deadlock -
we don't use timeouts for this.
Did you get unresolved deadlocks?
If so then there is a bug in lock manager.
