+
+ 1.) If the kill() in an older CRTL uses sys$forcex, causing the
+ target process to do a sys$exit, which usually can't be handled
+ gracefully...certainly not by Perl and the %SIG{} mechanism.
+
+ 2.) If the kill() in the CRTL can't be called from a signal
+ handler without disappearing into the ether, i.e., the signal
+ it purportedly sends is never trapped. Still true as of VMS 7.3.
+
+ sys$sigprc has the same parameters as sys$forcex, but throws an exception
+ in the target process rather than calling sys$exit.
+
+ Note that distinguishing SIGSEGV from SIGBUS requires an extra arg
+ on the ACCVIO condition, which sys$sigprc (and sys$forcex) don't
+ provide. On VMS 7.0+ this is taken care of by doing sys$sigprc
+ with condition codes C$_SIG0+nsig*8, catching the exception on the
+ target process and resignaling with appropriate arguments.
+
+ But we don't have that VMS 7.0+ exception handler, so if you
+ Perl_my_kill(.., SIGSEGV) it will show up as a SIGBUS. Oh well.
+
+ Also note that SIGTERM is listed in the docs as being "unimplemented",
+ yet always seems to be signaled with a VMS condition code of 4 (and
+ correctly handled for that code). So we hardwire it in.
+
+ Unlike the VMS 7.0+ CRTL kill() function, we actually check the signal
+ number to see if it's valid. So Perl_my_kill(pid,0) returns -1 rather
+ than signalling with an unrecognized (and unhandled by CRTL) code.
