Looks good, except for the test case:

+  (pass-if-exception "handler arg is an invalid integer"
+    exception:out-of-range
+    (sigaction SIGINT 51))

whereas my bits/signum.h shows:

#define SIGUNUSED 31

#define  _NSIG    65 /* Biggest signal number + 1
               (including real-time signals).  */

I presume that in the era of 64-bit CPU's we might
start seeing new sigs in the 32-64 range.  Or maybe
the RT kernels already do ... ?
