I'm not clear how this:
size_t os::Linux::min_stack_allowed = 2240 * K;
relates to all the values specified in the header file ??
Overall changing the default stacksizes for all threads this way seems
somewhat excessive to me - do you really need it for every Java
application? If builds are just the issue, and javadoc invocations in
particular, I would adjust the build settings.
