I understand your argument, and offer the following, which is from the 
same section of the python docs:

     "On other Unix systems (such as FreeBSD), the following attributes 
may be available (but may be only filled out if root tries to use them):

  * |st_birthtime| - time of file creation"

Suggesting that it's not "anti-POSIX" (unPOSIX?  aPOSIX?) to provide the 
information if it's available.

Anyway, I've found a more or less suitable workaround for now, batching 
up the queries and calling out to the shell - so I'll leave it at that.
