Does anyone know if the ftp proxy functionality in ipnat has been fixed on
non-x86 (sparc64, specifically) yet?

I first noticed FTP problems when I switched from an x86 box as the NAT
machine to an Ultra 1 170E. With the same dated current sources, everything
worked fine on the x86 nat machine, but when i switched, FTP was mostly
broken. For example, here is how it behaves on a LAN with a NetBSD/i386
1.6.2_STABLE NAT box:

dive@straylight:/tmp % ftp ftp://ftp.netbsd.org/pub/NetBSD/README

On another LAN with NetBSD 2.99.9/sparc64 as the nat machine (the *only*
difference in the ipnat.conf is hme's instead of rtk's), I see this:

I've mentioned this bug before, but nobody ever really acknowledged it...
should I send a critical/high PR? or can someone nudge the right people
(darrenr?) to fix it? I kinda need FTP for pkgsrc to function :)

Note that the on-quit hang is not the only symptom here... it dies on ls on
some servers, doesn't even finish logging in on others... so I'm pretty
certain the problem is in the ftp proxy code.
