 for context, the program to use this API and suffer hard from its
 brokenness is firefox which crashes often at runtime.
 There was some attempt to patch it in pkg/51966 which shouldn't
 have helped (it's for multiprocess, so pthread is no good) but
 seemed like it did.

 Will make it crash very quickly from lack of locking.
