a question about RTEMS notepad

[strauman at slac.stanford.edu (Till Straumann)]

IMHO, since the notepads are zeroed
at task creation (earlier versions of
RTEMS left them undefined) they have
become really useful as 'light-weight' task
variables. Plus, their 'affiliation'
with a task context is more obvious
than in the case of a task variable.
