|  | It's not necessary to save any registers on the stack across syscall in
x86_64 __set_thread_area.  Don't waste cycles or bytes on it. |

|  | this was originally written for an early draft of the library where
non-standard functions would reside in a static library separate from
the shared libc.so, which would implement a pure standard. the idea
was not to depend on an implementation-dependent __syscall_ret
function in the main libc. but it turned out to be better to put
everything in a single library for both static and dynamic linking
uses, and thus the (incomplete) remnants of this feature were just
enlarging the source and binary. |

|  | note that object files using sigset_t (or struct sigaction) need to be
recompiled to work correctly after this fix. | 
|  | thanks to Peter Mazinger (psm) for pointing many of these issues out
and submitting a patch on which this commit is loosely based |
