With slony 2.0.2 I had similar problems. A CREATE INDEX on the slave
caused slony on the slave to block while inserting into the table which
eventually blocked the server during the log switch (TRUNCATE) which
eventually blocked everything else.

It occurs to me that the slony daemon should be able to get the
TRUNCATE command to abort if it takes too long.

Have a nice day,
