6988458: G1: assert(mr.end() <= _cm->finger()) failed: otherwise the region shouldn't \
be on the stack
Summary: The changes from 6941395 did not clear the CMTask::_aborted_region fields \
when concurrent marking aborted because of overflow. As a result, the next time \
around we could see a memory region whose start address was above the global finger \
and the assertion tripped. Moved the clearing of the aborted regions to \
ConcurrentMark::clear_marking_state, which is executed on all of the \
exit paths.

6991377: G1: race between concurrent refinement and humongous object allocation
Summary: There is a race between the concurrent refinement threads and the humongous \
object allocation that can cause the concurrent refinement threads to corrupt the \
part of the BOT that it is being initialized by the humongous object allocation \
operation. The solution is to do the humongous object allocation in careful steps to \
ensure that the concurrent refinement threads always have a consistent view over the \
BOT, region contents, and top. The fix includes some very minor tidying up in \
sparsePRT.

6992998: CMSWaitDuration=0 causes hangs with +ExplicitGCInvokesConcurrent
Summary: Closed a timing hole during which concurrent full gc requests can be missed. \
The hole can increase the latency of the response to a full gc request by up to the \
value of CMSWaitDuration. If CMSWaitDuration=0 is, as currently, interpreted as an \
unbounded wait, suitable in certain tuning scenarios, the application can potentially \
hang. Made two obscure tunables, including CMSWaitDuration, \
manageable.
