I don't see why you would need to change what you are doing unless your 
application
whines about the symlink.  I.e. VirtualBox didn't like me using a symlink
in /opt to /home/opt on linux, so I mounted it w/a line in fstab.

/home/opt /opt  none  rbind 0 0

I don't know the state of cyg's support in those areas, so if you were 
forced
to change, you'd get to do your own testing to see what worked, etc.

I went one further under 'run' and 'tmp' -- I left those as public 
directories
and put my UID or login name as my own directory under the common name.

yeah 28k is nothing.  I was using files measured in MBytes though the 
[server]
system has over 100GB mem.  The communication goes through unix-sockets, 
which
also goes through /dev/shm, but its cleanup is technically the 
responsibility
of the OS, so, if lucky -- it cleans it up, if not, no worse off than 
before.

I don't run many OS progs on my Win machine cuz Win tended to flake out 
in running
tasks and wouldn't say anything when it went wrong.

So now, I just have a cronjobs on my linux server that use ssh to login 
to run
jobs on windows...
