Elena, here's a brief breakdown:

                  ptrace-exec         gcj-gc            gcj             
Java-GNOME
FC-5             broken(1)       broken(3)        ok                      ok
FC-4             broken|ok(2)       ok             broken(4)        
mega-rpm(5)
RHEL4           ok                    ok                 ok    
             mega-rpm
badger             ?                       ?               
broken(6)          missing(6)

(1) ptrace, when the non-main thread does an exec, is broken; on FC-5 
blocker list?
(2) see (1); broke it latest kernel; workaround is to avoid the latest 
kernel
(3) the garbage collector deadlocks; fix looming
(4) FC-4 gcj is missing fixes found on RHEL-4; workaround by building 
installing RHEL-4 gcj snapshot
(5) Assuming (4) installed; the RHEL-4 mega-rpm can be built and installed
(6) Breezy Badger needs both upstream compiler, and upstream Java-GNOME 
bindings to build.

So as soon as those two remaining FC-5 issues are fixed (I think gcj-gc 
is about to go through); I'd agree that we can switch.
