+# scientific applications started by the boinc client, there is a chance for
+# the boinc client not to be granted sufficient opportunity to check for
+# scientific applications to be alive and make the (wrong) decision to
+# terminate the scientific app. This is particularly an issue with many
+# apps started in parallel on modern multi-core systems and extra overheads
+# for the download and uploads of files with the project servers. Another
+# concern is the latency for scientific applications to communicate with the
+# graphics card, which should be low. All such values should be set and
+# controled from within the BOINC client. The Debian init script also sets
+# extra constrains via chrt on real time performance and via ionice on 
+# I/O performance, which is beyond the regular BOINC client. It then was
+# too easy to use that code to also constrain minimal nice levels. We still
+# think about how to best distinguish GPU applications from regular apps.
