RFR(XXS): 8249150: SA core file tests sometimes time out on OSX with "java.io.IOException: App waiting timeout"

[Chris Plummer]

Hello,

Please help review the following:

https://bugs.openjdk.java.net/browse/JDK-8249150
http://cr.openjdk.java.net/~cjplummer/8249150/webrev.00/index.html

The tests in question use recently added LingeredApp support for dumping 
a core file. On OSX a core file dump sometimes takes a very long time, 
exceeding the amount of time Lingeredapp.waitAppReady() is willing to 
wait. This wait time needs to be increased to allow the core file to 
finish dumping, and also a couple of the tests that use the LingeredApp 
core file support need longer test timeouts. Note ClhsdbFindPC already 
has a long timeout, so no timeout changes were needed for it.

Tested by running all serviceability/sa tests once on all platforms, and 
400 times on OSX (200 regular runs and 100 -Xcomp runs).

thanks,

Chris
