[kaffe] kaffe debug output

[Mark and Janice Juszczec]

Hi folks

A few days ago I sent the output of running kaffe with -vmdebug ALL to the 
list.  Dalibor wondered why calls to initCollector()
were missing and suggested I use the CVS snapshot.  Below is the output from 
-vmdebug ALL with CVS code from 01/02/04.

initCollector() calls are present.

Why is it trying to add Klasses.jar to the classpath?  Wasn't it replaced by 
rt.jar?
Also, the 2nd to last line mentions freelist 0.  Is this ok?

Does it makes sense to double check the alloc'd/free'd amounts of memory?

Mark
