- * TODO:
- * Rename sigsetjmp to __sigsetjmp and siglongjmp to __siglongjmp,
- * remove the other *jmp functions and define everything in terms
- * of the renamed functions. This requires compiler support for
- * the renamed functions (introduced in gcc-2.5.3; previous versions
- * only supported *jmp with 0 or 1 leading underscores).
- *
- * Use sigprocmask() instead of sigblock() and sigsetmask(), and
- * check for and handle errors.
- *
- * Restore _all_ the registers and the signal mask atomically. Can
- * use sigreturn() if sigreturn() works.
