We should remember this bug, at least.  If the bug database is working 
(http://cgi.kaffe.org/cgi-bin/kaffe) could you file a report on this?

This assert is from an older version of Kaffe (the 1.0.5 snapshot from 
8 months ago...).  If you could upgrade to the CVS version (see
http://www.kaffe.org/CVS.html), that would be helpful.

You are debugging Kaffe at this point, so anything you can give us is
appreciated!  :)

Is there any way I could get hold of a .jar for this to debug Kaffe
here?  I should probably just write a small test case that hammers on
local sockets...  Any chance I could get the source to
AsyncSocketThread?  :)
