[PATCH] Linux implementation for set_native_thread_name()

[Roman Kennke]

Hello,

The following patch implements set_native_thread_name() for Linux, which
was so far unimplemented. The name needs to be truncated to 15 chars,
otherwise it would not be accepted by pthread_setname_np() at all.

This is my first patch to hotspot ever, so please let me know when I did
anything fundamental wrong. I have another patch in the pipeline for
implementing the other 2 missing methods in the same source file
(distribute_processes() and bind_to_processor() ).

What do you think?

Kind regards, Roman
