# We need two slave threads here to guarantee progress.
# If we use only one thread the following could happen
# in node_1:
# We block the only slave thread in wsrep_apply_cb and we
# issue an INSERT (by calling the stored procedure) that will
# try to acquire galera's local monitor in pre_commit().
# This usually works fine, except for when a commit cut event
# sneaks in the slave queue and gets a local seqno smaller than
# that of the INSERT. Because there is only one slave thread,
# commit cut is not processed and therefore does not advance
# local monitor, and our INSERT remains stuck there.
