There is no "problem" in Ada or X11, the problem is that you are
trying to use an Ada run-time system which is not
SIGALRM-friendly. The fact that your Ada run-time catches SIGALRM can
hardly be seen as a "problem in X11 (as usual)". Using GNAT, I've
built applications that use delays as well as X11 and I have never
encountered such a behaviour.
You should try to compile your project with another compiler and see
if the same thing happens (GNAT is freely available from
ftp://cs.nyu.edu/pub/gnat/ for example).
