CVS commit: src/usr.sbin/puffs/mount_psshfs

Module Name:    src
Committed By:   pooka

Modified Files:
        src/usr.sbin/puffs/mount_psshfs: node.c psshfs.c psshfs.h subr.c

Log Message:
Introduce the concept of lazyopens.  This means that when a file
handle open is requested, it is waited for only if the node was
not previously succesfully opened.  The actual wait for the file
handle happens only when the file handle is actually needed (read
or write).  This in turn has the effect that reading cached files
will be quick instead of waiting for the file handle from the sftp
server first.  The wait previously could be very long if there were
serveral hundred k of outstanding requests in a limited-bandwidth
link.

The code is in some need of serious handholding, but it works, so
I'll leave that as "future work".
