This makes it possible to make the same code run in the same mode as
libthr.

we have not compared them for performance yet.
it is also not fully decided how this will be done in production..
will we have 2 libraries and selct one? Or will it be possible to 
use a run-time selector?
At the moment it is a compile time selection as to which you make and
a run-time (via libmap) decision wich you link to..

We'll probably make a libpthread-1:1.so and a libpthread-m:n.so.
As they are the same code the interface is pretty much guaranteed to be
the same.. Note that like libthr, the 1:1 version is incapable of doing
process-scope threads, but otherwise they are compatible.

David and Dan (The dynamic "D"s) have been working incredibly hard on
this..

Thanks guys!
