-    During analyze of Bug#38133 (Myisamlog test fails on Windows)
-    I met the situation that the program myisamlog locked the file
-    exclusively, then additionally shared, then did one unlock, and
-    then blocked on an attempt to lock it exclusively again.
-    Unlocking before every lock fixed the problem.
-    Note that this introduces a race condition. When the application
-    wants to convert an exclusive lock into a shared one, it will now
-    first unlock the file and then lock it shared. A waiting exclusive
-    lock could step in here. For reasons described in Bug#38133 and
-    Bug#41124 (Server hangs on Windows with --external-locking after
-    INSERT...SELECT) and in the review thread at
-    http://lists.mysql.com/commits/60721 it seems to be the better
-    option than not to unlock here.
-    If one day someone notices a way how to do file lock type changes
-    on Windows without unlocking before taking the new lock, please
-    change this code accordingly to fix the race condition.
