Comment (by soulseekah):

 Hey there, welcome to Trac! Thanks for your ticket.

 WordPress operations are non-atomic. WordPress on the whole is not thread-
 safe. This means that calling most of the APIs that interact with the
 database is risky.

 If you need to protect your resources from concurrent operations you'll
 have to perform synchornization (mutexing) yourself.

 Rewriting WordPress to be thread-safe means rewriting like 80% of its
 APIs... a very daunting task. To my knowledge there haven't been any
 attempts at even trying to include synchronization to API calls. Perhaps
 it's time...
