Subject Re: [arch] The Third Way : C/C++ and Java and lets go forward
Date Mon, 23 May 2005 18:29:16 GMT
(for the record, this isn't about "not doing Java" or "not doing  
JikesRVM", but rather my understanding that we'll need a small C/C++  
kernel to host the modules, no matter how they are written, and this  
is a way to get that going...)
