Where does he have that information from? The Solaris 9 manual page says:

     ____________________________________________________________
    |       ATTRIBUTE TYPE        |       ATTRIBUTE VALUE       |
    |_____________________________|_____________________________|

    |_____________________________|_____________________________|

That mean it *is* thread safe.

A memory large enough for the whole dump files would dramatically increase
the memory footprint of "milter-greylist". And you don't know how large the
buffer needs to be. Writing code for which manages a small buffer means
reimplementing a lot of stdio.

I disagree. It would mean writing and maintaing a lot of extra code just
because of a problem with 32Bit binaries under Solaris.
