Known wait/notify bugs in Kaffe? I think I've found one.

[Gary Howland]

Hi,

I've been using wait/notify in conjunction with the Biss library.  When I run 
my application using Suns JDK on FreeBSD, it works as expected.  When I run it 
using kaffe .83, it doesn't.  Are there any known wait/notify problems?

I can package up my code and make it available for anyone who is interested 
into looking in to the problem further. 

Here is the section of code that is causing the problems, but it may not mean 
much yanked out of context like this ...

The problem is that the waitForClose() method does not return under certain 
circumstances (but the problem is 100% repeatable, and works under Suns JDK)
