Set to temporarily ignore calls to wakeup_subsequent_commits(). The
caller must arrange that another wakeup_subsequent_commits() gets called
later after wakeup_blocked has been set back to false.
This is used for parallel replication with temporary tables.
Temporary tables require strict single-threaded operation. The normal
optimization, of doing wakeup_subsequent_commits early and overlapping
part of the commit with the following transaction, is not safe. Thus
when temporary tables are replicated, wakeup is blocked until the
event group is fully done.
