    My fault for not reading up on how to protect critical code with 
 sigprocmask().  ie: 
 http://ou800doc.caldera.com/en/SDK_sysprog/_Protecting_Critical_Sections.html
 
    This technique works to protect the code from qemu's use of SIGALRM 
 as a timing mechanism.  There are a few more issues with my code, but 
 they are my issues.  Sorry for the stirrup.
