I'm a little scared by this module.  Besides the multitudes of compile
warnings, this little assertion came up for me when I ran the code above.

Assertion !((((_svi)->sv_flags & (0x00004000|0x00008000)) == 0x00008000)
&& (((svtype)((_svi)->sv_flags & 0xff)) == SVt_PVGV ||
((svtype)((_svi)->sv_flags & 0xff)) == SVt_PVLV)) failed: file "SSH2.c",
line 2350 at
/usr/lib/perl5/site_perl/5.10.0/i386-linux-thread-multi/Net/SSH2/Channel.pm
line 14.
        (in cleanup) Assertion !((((_svi)->sv_flags &
(0x00004000|0x00008000)) == 0x00008000) && (((svtype)((_svi)->sv_flags &
0xff)) == SVt_PVGV || ((svtype)((_svi)->sv_flags & 0xff)) == SVt_PVLV))
