I sometimes get behind in my mail.  :-)
Right now there's 1.6 Mb in my /usr/spool/mail file.
I read the stuff w/ mailtool on a SunOS 4.0 machine.

I noticed that compiles were failing w/ write error: / file system is full
and traced it down to this:

When the mailtool is fired up, df shows 1.6 Mb less space in /.  OK, I
thought there's some temporary file in /tmp holding all this garbage.
But ls couldn't find anything in /tmp, and du couldn't find anything in 
/tmp, as a matter of fact du of all directories in the root partition
doesn't turn up anything 1.6 Mb in size.  Hmmmm.

``ofiles'' (thank god for ofiles) shows Mail has an open inode, 1788, 
on the root file system.  But "find / -inum 1788 -xdev -print" shows
nothing.

So, what is this bizarre object?  Ofiles and df know about it.
du, ls, and find don't know about it.

Thanx,
