|what exactly is a native thread?? (something using pthreads on linux??)

I meant thread library which is provided along with OS, i.e. pthreads
on many flavors of UNIX, Win32 threads on Windows.

|what is the advantage / disadvantage of the ruby approach to threads??

Ruby's is slow but portable.  It runs everywhere (even on plain DOS).

|are native threads faster??

In general, yes.

|Does anybody know, if the Python and Perl Thread implementations are similar

They are using native thread.  Python uses giant interpreter lock (I
think it still uses the global lock).  Perl uses per thread interpeter
struct.
