Merge pull request #124 from rmetrich/basic_loglock
Changed log lock from 'quick' to 'basic' because this is an I/O lock.

d63cb99649 Changed log lock from 'quick' to 'basic' because this is an I/O lock.
We cannot use a 'quick' lock (i.e. lock spinning on the CPU) for the log
lock because it can wait a lot on I/Os. Using a 'quick' lock leads to
eating the CPU for no good reason.

Example of 'pidstat' output when using various locks for log_lock:

- 'quick' lock and slow log file system (tail -f on the log file on XFS on RHEL 8)

We can see in the above example, when 'basic' lock is used, that CPU
isn't consumed when log file system is slow.

Another reproducer scenario: put the log file on a NFS share with 'sync'
option.
