Deadlock detected after pg_repack receives SIGINT

I'm running a pg_repack from a bash script with timeout of 10 minutes like
so (simplified version):
timeout -s SIGINT 10m pg_repack --table=frequently_updated_table

After the 10 min timeout, the OS sends SIGINT to pg_repack process so the
pg_repack calls:
SELECT repack.repack_drop($1, $2)
and it causes a deadlock with other process which is INSERTing into
frequently_updated_table that has a pg_repack's trigger to log every change
to a repack.log_[OID of frequently_updated_table].

Is it a bug of pg_repack or am I doing something wrong? Should I add some
detailed info?

Thank You for any help,
Jiri

PS: I was trying a mailing list of pg_repack (http://lists.pgfoundry.org/pipermail/reorg-genera) and github without any notice. If there is better place to ask, tell me, please.
