Request for review: 7059899: Stack overflows in Java code cause 64-bit JVMs to exit due to SIGSEGV

[Chris Hegarty]

Karen,

One of the issues that provokes this problem is the native networking 
socket read/write code on unix. When running a 64bit JDK the read/write 
implementation can try to create an on stack buffer of up to 128K. I 
believe this may have been greater than the old StackShadowPages size.

-Chris.
