We've to allocate a variable which we simply don't need. Look,
the former code reads the flag, puts it into variable then
immediately read it and that's all :/ I think we should not
spread @is_sync but read the flag as much as possible for
better grep'ability.

Of course there are places where read-once variable is preferred
but this is not our case.
