Re: [9fans] tarfs & 2GB limit

[erik quanstrom <quanstro@quanstro.net>]

there is no p9p tarfs. i keep a copy of (what i thought was)
an up-to-date plan9 dist here so i can easily grab stuff that hasn't 
been ported.

the 2GB filesize limit of tarfs is due to the long "off" passed 
to doread. i'm working on it.
