> We observer that Storm_Nimbus, storm_supervisor and NMStormTopology is consuming 100%
CPU with all CPU cores. 
> We found that Dispatcher Thread is taking quiet lot CPU. We observer that this issue
was also reported earlier in Jira with title "{color:#333333}Short disruptor queue wait time
leads to high CPU usage when idle{color}"

> This say the issue got fixed in the version 0.9.6 while in the version 1.0.0 seems the
issue is still fixed.

has this issue resolved.
