------- Comment #2 from braddr at puremagic.com  2007-10-14 16:40 -------
downs:  I saw your comments in scrollback on irc.  Two comments:

1) thanks.. you're right about the need to globally synchronize and not
per-class-instance synchronize.  I've fixed that:

- synchronized he = gethostbyname(toStringz(name));
+ synchronized(this.classinfo) he = gethostbyname(toStringz(name));

2) Regarding the use of static if, that would only work if there was sufficient
configury mechanics to make sure that the _r versions were only included if
they exist.  All static if can see is what's been declared, not what actually
is linkable.  My main objection isn't really the declaration part of _r, but
the very wierd usage of needing to grow that buffer and iterate many times. 
That'd likely end up more expensive than just synching.

Thanks for catching #1.

Later,
Brad
