To support multiple APIs. Each API can specify the prototype of the
task/threads it supports. RTEMS tasks and POSIX threads are prototyped

To allow a remote task to block.

Notepad is simply a set of 16 32-bit entities that can be manipulated by
the application via the rtems_task_set_note and rtems_task_get_note
One notepad is reserved for use by newlib.
IMO notepads are the worst thing in the RTEID/ORKID specification the
RTEMS Classic API is based on. POSIX keys provide similar functionality
in a more useful fashion.
