I might have a use for such a server for a project I'd like to
share on the net (a-la sourceforge but with SVN).
A tcptraceroute shows that it's located in Taiwan. Is it
a reliable server with reliable conneciton? Is it praticle
to relay on it?
Thanks,

Here is another potential issue:

In any case, the whole point is moot: one should *never* write code
that will only execute correctly on a single-CPU system and break on
SMP.

There are test-and-set instructions for example :
68000 has tas, SPARC has ldstub etc.
Upon return the value is set to the address. The return value varies - if the value really changes or not.

Well AS ES WS segmentation is mainly a marketing issue.
AS simply has more packages in them but if you check you'll see that
they'll work on an ES or WS as well.
They share the same kenel rpms.
These are the kernels in AS3 and ES3:
