Looking at the fuse man page, it appears that if one uses EncFS atop a network 
file system, the mount should not use the kernel_cache option, and should use 
the auto_cache option or perhaps ac_attr_timeout=0 (the man page is unclear 
about all this, unfortunately).  Perhaps EncFS should use appropriate settings 
for these options by default if it determines that the underlying file system is 
network-based.

Anyway, assuming "-o attr_timeout=0" (or something similar) solves the problem, 
we do have a workaround now.
