-/* Under GNU/Linux, signal handler invocations can be identified by the
-   designated code sequence that is used to return from a signal
-   handler.  In particular, the return address of a signal handler
-   points to the following sequence (the first instruction is quadword
-   aligned):
-  
-   bis $30,$30,$16
-   addq $31,0x67,$0
-   call_pal callsys 
-      
-   Each instruction has a unique encoding, so we simply attempt to
-   match the instruction the pc is pointing to with any of the above
-   instructions.  If there is a hit, we know the offset to the start
-   of the designated sequence and can then check whether we really are
-   executing in a designated sequence.  If not, -1 is returned,
-   otherwise the offset from the start of the desingated sequence is
-   returned.
-   
-   There is a slight chance of false hits: code could jump into the
-   middle of the designated sequence, in which case there is no
-   guarantee that we are in the middle of a sigreturn syscall.  Don't
-   think this will be a problem in praxis, though.  */
