* OpenSSH sftp-server can read requests faster, than it processes
them, when it's buffer is full it aborts. This can happen on a
large upload to a slow server. Work around this by limiting the
total size of outstanding reqests. Debian bug #365541. Tracked
down by Thue Janus Kristensen
* Add --disable-sshnodelay configure option. The sshnodelay.so
hack shouldnt be needed with OpenSSH client versions >= 4.3
The hack pre stripped so this fixes that too:
* QA Notice: Pre-stripped files found:
* /var/tmp/portage/sys-fs/sshfs-fuse-1.8/image/usr/lib/sshnodelay.so
strip: i686-pc-linux-gnu-strip --strip-unneeded
