 There has been extensive testing of the baseline simulation of integer
 and FP instructions.  Memcheck is also believed to work, at least for
 small examples.  Other tools appear to at least not crash when running
 /bin/date.
 
+Enough syscalls are supported for /bin/ssh and /bin/bash to work.  In
