Comment 11 for bug 1002714

Indeed, it is specific to SST and
1) if I understand correctly, FTWRL does a read lock - i.e. it still allows reads from client - and if client requires causality, then such read will block (for 30 seconds and it is not controlled by lock_wait_timeout)
2) with regards to mysqldump lock_wait_timeout still does not really help: some (if not all) clients will block in commit.

Otherwise I guess everything is good, I'll push it after some more testing.
