Prior to Redhat 7.1 with 2.4 kernel, thread stack size on Linux is fixed
at 2M for each thread, therefore the flag -Xss was disabled for Java on
Linux. However, with the introduction of floating stack in Redhat 7.1,
thread stack size can be changed by user application. "-Xss" should be
supported for RH 7.1. Also, having a smaller default stack size (instead
of the huge 8M stack set by the OS) may boost the thread creation speed.
