Speaking of which, I wonder what would happen if a 64-bit process makes
a 32-bit system call (using int 0x80, for example), and gets a signal.

I guess that's the next patch. And I see amluto has some concerns...

/me goes read.

In the next revision, there will be no "signal context extension" 
struct.  However, the flow for 64, ia32 and x32 will be similar.  I will 
send that out after some testing.
