Now we want to open this next log. To know if it's a hot log (the one
being written by the I/O thread now) or a cold log, we can use
is_active(); if it is hot, we use the I/O cache; if it's cold we open
the file normally. But if is_active() reports that the log is hot, this
may change between the test and the consequence of the test. So we may
open the I/O cache whereas the log is now cold, which is nonsense.
To guard against this, we need to have LOCK_log.
