+ Anal operating systems like SGI Irix and Compaq Tru64 adhere
+ strictly to the letter of the law, so our hack doesn't work.
+ The following fragment from an Irix header file is suggestive:
+
+ #ifdef __notdef__
+ // this is not currently supported
+ #define TIOCSIGNAL (tIOC|31) // pty: send signal to slave
+ #endif
+
+ On those systems where none of our tricks work, we just fall back
+ to the non-current_group behavior and kill the process group of
+ the child.
