I'm still seeing the problem.  My tmpfs, which is configured in fstab as 

tmpfs           /tmp            tmpfs   rw,-s=600m

Is, currently, shown with df -k:

Filesystem   1K-blocks       Used      Avail %Cap Mounted on
tmpfs            163580          4     163576   0% /tmp

I don't know if it was this small when I booted, but after a -j 5 ran 
out of space in /tmp, this is what I see.

   So this is still a problem in current -current (5.99.45).  I again today had 
a 160MBish /tmp, with the fstab as above (-s=600m).  Without a -s option at all 
it's still 160MBish.  Mounting /tmp with mfs works as expected.

   I'll go make sure there isn't a PR for this, and file one if there isn't.

I've filed PR kern/44629 for this. If anyone has any ideas, or patches they want me to try, just let me know. Thanks.
