[LITMUS^RT] Hit crash in C-EDF (configured as partitioned)

[Hiroyuki Chishiro]

Hi Björn,

I tried the following patch patterns in the PFAIR plugin on a quad-core
processor.

The task set is as follows.

--
./setsched PFAIR
sleep 1
./rtspin -w 4 5 10 &
./rtspin -w 4 5 10 &
./rtspin -w 4 5 10 &
./rtspin -w 4 5 10 &
./rtspin -w 4 5 10 &
sleep 1
./release_ts -d 3000 &

github's original: hit bheap_delete() bug
Jonathan's patch: hit bheap_delete() bug
Latest patch: hit bheap_delete() bug

I think that the problem has not completely solved.
