<rbb raises hand>

APR has called this out from the get-go. The data is associated with
whatever pool is used to open the file. The user-data stuff is an aspect
of pools, not every APR type. If we tried to associate the data with the
specific file handle, we would need a hash-table in every APR type, as
well as one in the pool. You must name your key so that it won't
interfere with other keys in the pool. This used to be very clearly
documented, but I haven't touched that code in well over a year, so I
don't know if it still is or not.
