+ Behavior of
+ asynchronous signals depends on the target environment.
This is too vague. Can we at least mention the possible behaviors, or
just the most common/expected ones? The reader should get some idea
of what might happen.
You didn't change anything in response to this comment.
Well, I don't really have any idea what might happen --
and it's really out of GDB's hands. The target might do
(almost literally) anything. It might ignore asynchronous
signals completely. It might record and reproduce them
faithfully. It might stick them in randomly.
Well, for starters, even the above text should be better than
nothing.
Honestly, rather than insert an entire paragraph about how
we don't really understand how it will behave, I'd feel better
just removing the sentence that mentions asynchronous signals.
However, don't you have at least one target that supports reverse
debugging? If so, we have at least one specific type of behavior we
can describe, don't we?
a) I'm not sure what it does
b) I'm not sure if the implementer of my target gave it any thought
c) I've no reason to believe that another target would behave
at all similarly.
You left "backward" in the text.
Um, yeah... Eli, the text already contains "backward" twice, and
"backwards" only once, including *both* phrases "search backward"
and "search backwards". I'm not convinced one is more correct
than the other, nor that a consistant usage is demonstrated in
context.
That said, I guess I don't care all that strongly -- but "backward"
sounds more correct to me here.
My local English grammar guru claims that ``backwards'' is the correct
usage; ``backward'' as an adjective means ``retarded''.
Well, as a native speaker, I disagree with your guru,
and so does dictionary.com: that meaning is only the
third listed. Note especially the "usage note" at the end.
