Hi list,

I found a minor bug in uslurp(int pid, const char* name).  It doesn't
append a NUL character.  MapsBuilder.construct then throws an exception:

Exception in thread "Thread-1" java.lang.RuntimeException: missing NUL
   at frysk.sys.proc.MapsBuilder.construct(fltrace)

The attached patch fixes this problem, and introduces no regression.
(Tested against fresh checkout.)

Thanks,
