I wanted to add to this in hopes someone might be able to confirm this
or know how to fix it even. I have it happen just about every time
and it doesn't seem to be limited to just certain hosts. I'm
typically using libssh2 on an OS X machine, but I also just tried
building it on a linux VM (turnkey linux) and connecting to a couple
different servers. the test app (scp_write edited for specific file
etc.) always hangs on waiting for the channel to close, and the
uploaded file is corrupt (25MB zip file)

still poking around some but I'm pretty clueless. SFTP so far works
just fine.
