About entanglement between nio Bits and
ExtendedCleaner.retryWhileHelpingClean(). It is the same level of
entanglement as between the DirectByteBuffer constructor and
Cleaner.register(). In both occasions an action is provided to the
Cleaner. Cleaner.register() takes a cleanup action and
ExtendedCleaner.retryWhileHelpingClean() takes a retriable
"allocating" or "reservation" action. "allocation" or "reservation" is
the opposite of cleanup. Both methods are encapsulated in the same
object because those two functions must be coordinated. So I think
that collocating them together makes sense. What do you think?
...to illustrate what I mean, here's a variant that totally untangles
Bits from Cleaner and moves the whole Cleaner interaction into the
DirectByteBuffer itself:

Notice the symmetry between Cleaner.retryWhileHelpingClean :
Cleaner.register and Allocator : Deallocator ?
