PR 1212/cpukit
* rtems/src/taskmode.c, score/src/threadtickletimeslice.c: Time slicing
will not happen if the task mode is changed from a non-timeslicing
mode to timeslicing mode if it is done by the executing thread (e.g.
in its task body). This change includes sp44 to demonstrate the
problem and verify the correction.
