[Seán Coffey]

Requesting approval to push Alan's following inter-related fixes from 
jdk8 to 7u6 :

7169050: (se) Selector.select slow on Solaris due to insertion of 
POLLREMOVE and 0 events

7173515: (se) Selector.open fails with OOME on Solaris when unlimited 
file descriptors

One changeset should work for jdk7 since they're related. Performance 
test teams have been testing the 7u patches without issue.

regards,
Sean.
