Comment (by swissspidy):

 Why limit this to post meta? The same race conditions can happen with
 ''every'' table and entry.

 WordPress currently doesn't use table/row locks as these are dependant on
 the storage engines and not guaranteed to be available all the time. Also,
 using multiple database servers needs to be considered.

 All in all, it's not as trivial as it sounds.
