It is not irrelevant, but its wording is obscure and unclear, at least
to me. The full comment reads:
+ /* Resume main thread if we are attaching to a suspended
+ process.
+ Note that we are not trying to handle multi-threaded
+ situations, as these are likely to be too complex anyway.
+ This is primarily meant to cover the case where someone
+ creates a process in suspended state and hands it over
+ to gdb (this is an abstraction - you cannot actually do
+ that due to Windows bugs. You need to start debugging the
+ process yourself, and once it has started up, you suspend
+ it and detach from it). */
Perhaps I read this too naively, but note how you first seem to
describe a use-case:
This is primarily meant to cover the case where someone
creates a process in suspended state and hands it over
to gdb
but then immediately say that it cannot be done:
this is an abstraction - you cannot actually do
that due to Windows bugs.
After reading this, I already become confused.
You need to start debugging the process yourself,
and once it has started up, you suspend it and detach from it
And now I'm _really_ confused: ``detach''? didn't you say ``attach''
above? why detach from a process if you want to debug it?
Of course, Chris knows much more than I do about debugging on Windows,
so perhaps his difficulty with your concept was different and more
deep. I will let him speak for himself.

When your assertions are not clearly worded, it is customary to ask
questions. Asking questions is not ignoring; quite the opposite: it
means your work is of interest and of importance.

I find nothing rude in Chris's question.
