See Postfix run on ZFS

postfix compiles on OpenSolaris
postfix runs
postfix tries to accept email
postfix uses statvfs to enquire free space on /var/spool
/var/spool is on ZFS with > 2TB free space
statvfs dies (EOVERFLOW)
postfix dies
poor email

UPDATE: small patch fixes this, assuming that an FS with more than ULONG_MAX/2 free blocks has — for all purposes of postfix — exactly ULONG_MAX/2 free blocks.
