The process priority of the kernel
was increased manualy with the ps.exe / nice.exe pair
form the unix95.zip archiv.
One can find it on
ftp.cica.indiana.edu:/pub/pc/win32/sysutil/unix95.zip
The other tasks and the system was still usable, especially
the frontend works fine.
I had make only one run with every configuration, always
with a fresh loaded kernel.
All othe tasks had normal priority.
