I verified it more carefully.

All these were conducted using lock.l_start=0, lock.l_len=0 (ie.
locking whole file; otherwise the last case won't work)

Case                     OS              FS            Result

fcntl() alone            Solaris 2.6     local UFS     OK
fcntl() alone            Solaris 2.6     NFS           OK
fcntl() alone            Solaris 8       local UFS     OK
fcntl() alone            Solaris 8       NFS           OK
mmap(file); fcntl(file)  Solaris 2.6     local UFS     OK
mmap(file); fcntl(file)  Solaris 8       local UFS     OK
mmap(file); fcntl(file)  Solaris 2.6     NFS           ERR
mmap(file); fcntl(file)  Solaris 8       NFS           OK

Casper Dik suggested to check at runtime whether mmap(file); fcntl(file)
fails and pass DB_NOMMAP accordingly. After some thoughts, maybe it's not
that bad idea. Perhaps something like that would do:

And now I start to peek inside datastore_db.c to try to fit some
code and what do I see? Eh. :)

Thanks guys.
