[8] Review request for 8015375: Edits to text components hang for clipboard access

[dmitry markov]

Hello,

Could you review the fix, please?
    bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8015375
    webrev: http://cr.openjdk.java.net/~vkarnauk/8015375/webrev.00/
The function XNextSecondaryLoopEvent() should use a progressive time out 
value instead of hardcoded 250 msces during secondary loop execution.

Thanks,
Dmitry
