* Source/callframe.m: callframe_do_call_opts(),
callframe_build_return_opts() fixed memory leaks.
Performance improvements -
callframe_from_info() use a single malloc to allocate memory for
the entire callframe. callframe_free() use a single free()
* Source/NSConnection.m: Wait only 0.1 millisecond for first try
checking for events ... CPUs are getting faster.
* Source/NSTimer.m: Set minimum timer to 0.1 milliseconds ...
