/ According to the iBCS2 book, signal() has 0x30 in %eax, and the address
/ of a function in %edx.  This function is where a signal handler will
/ return to; it should just adjust the stack pointer, and call $f,$0.
/ Strange but true.

/ The iBCS2 book also clears out %eax here, which seems to be broken.
