Optimize shmlog writing:

If we know the record length, only hold the mutex while we reserve
the space.  Until we change the first byte, nothing bad can happen.

XXX: a memory barrier is strictly speaking necessary before we assign
the first byte.

If there are no '%' in the format string, treat as fixed length for
speed.
