You don't have to bind it from another task or use it at all.

Hello,
I tried to have a look at this issue, but i it perhaps beyond my skills and xenomai knowledge.
I have found in the sources, that the EBUSY is returned by the xnheap_destroy_mapped (probably) because the heap->archdep.numaps still includes actual task/process/whatever.
So there should be some test if the current task isn't (accidentally ;-)) the only referring task. But maybe the fix will be more complex ;-(
Could you please fix it. It's strange that others don't have this problem with the new version...
TIA
