[sshfs] macfuse sshfs hangs on writes, debug log attached

[John O. <joh...@ya...>]

Howdy, I'm a new user of sshfs. I think it's a great program but I
have had trouble getting it to work. 

My system:

OS X 10.4.9 (PPC; PowerBook 1.67 GHz)
movenpick 500$ sshfs --version
SSHFS version 1.7
FUSE library version: 2.6.3
(from MacPorts)

My problem:

The remote file system hangs when writing text files. Only killing and
umounting it allows it to return to normal. This seems a little weird:
it never appears to fail on the first write but instead only on
subsequent writes. When it fails, I can try to list the directory
where it is mounted, but listing that directory hangs (tab completion
also hangs).

I have tried against multiple remote peers (both Windows and Linux),
so I think it's a problem with my sshfs, not the remote systems.

Log below is generated using 
shfs -odebug,sshfs_debug,loglevel=debug ...

This is the end of the log where it fails. It repeats the final line
forever. 

Thoughts?
