Hmmm - that might be the common lore.
DIST may indeed be the culprit rather than DDF enclaves.
Where I have seen this there is a *LOT* of enclaves being created - I presumed 
(without a lot of hard evidence) that the cost of setup/teardown was appearing 
in DIST. And, of course, DIST is an important address space, and runaway CPU 
consumption there hurts (almost) everyone else.

The OP indicated cancelling a single thread relieves the situation - should be 
easy enough to track down the likely suspect.
