Well, this all sounds good, but it doesnt help much. the clients can't have
all their own buffer files, because I run them from my home dir, which is
NFS mounted in the network, so they use all one buffer file. so I wanted to
set them up, with everyone its own checkpoint file.
i also cant run a perproxy, and this wouldnt also avoid that the work after
a few hours for the single machines is lost.
for better understanding : its a university network, and I am allowed to
run the client over night there sometimes, but with my account I have only
my (NFS-mounted) home directory available
