While working on the following bug:

4379126 3/5 Internal Error at os_linux.cpp, 1689 (Linux)

Karen noticed that the HotSpot implementation of GetCurrentThreadCpuTime()
was returning incorrect information. On Solaris and Linux, it returns
information relative to current system time and not current thread CPU
time.

My fix for the Linux crash leverages off os::elapsed_counter() and
I noticed that this function returns different information on Solaris
and Linux. On Solaris, the return is current_time - VM_start_time,
which is effectively how much time the VM has been up and running.
On Linux, the return is current_time. Not the same thing at all.
