*Don't* kill all local variables on function exit. This will be done
...
by the frameobject dealloc when it is time for the locals to go. When
there's still a traceback object referencing this stack frame, we
don't want the local variables to disappear yet.
(Hmm... Shouldn't they be copied to the f_locals dictionary?)

Two small changes:
...
- Use co->... instead of f->f_code->...; save an extra lookup of what
we already have in a local variable).
- Remove test for nlocals > 0 before setting fastlocals to
f->f_localsplus; 0 is a rare case and the assignment is safe even
then.

Plug a leak with calling something other than a function or method is
...
called with keyword arguments -- the keyword and value were leaked.
This affected for instance with a __call__() method.
Bug reported and fix supplied by Jim Fulton.

Patches for (two forms of) optional dynamic execution profiling --
...
i.e., counting opcode frequencies, or (with DXPAIRS defined) opcode
pair frequencies. Define DYNAMIC_EXECUTION_PROFILE on the command
line (for this file and for sysmodule.c) to enable.

Change the control flow for error handling in the function prelude to
...
jump to the "Kill locals" section at the end. Add #ifdef macintosh
bandaid to make sure we call sigcheck() on the Mac.

Instead of emitting SET_LINENO instructions, generate a line number
...
table which is incorporated in the code object. This way, the runtime
overhead to keep track of line numbers is only incurred when an
exception has to be reported.

Kill all local variables on function return. This closes a gigantic
...
leak of memory and file descriptors (thanks for Roj for reporting
that!). Alas, the speed goes down by 5%. :-(

Only call sigcheck() at the ticker code if we don't have true signals.
...
This is safe now that both intrcheck() and signalmodule.c schedule a
sigcheck() call via Py_AddPendingCall().
This gives another 7% speedup (never run such a test twice ;-).

Cleanup:
...
- fix bug in Py_MakePendingCalls() with threading
- fix return type of do_raise
- remove build_slice (same as PySlice_New)
- remove code inside #if 0
- remove code inside #ifdef CHECK_STACK
- remove code inside #ifdef SUPPORT_OBSOLETE_ACCESS
- comment about newimp.py should refer to ni.py

Changes for frame object speedup:
...
- get fastlocals differently
- call newframeobject() with fewer arguments
- toss getowner(), which was unused anyway

literals that look like identifiers. Also intern all strings used as

Add "if (x != NULL) continue;" (or similar for err==0) before the

break to most cases, as suggested by Tim Peters. This gives another
8-10% speedup.
