Re: [ros-dev] Send Messages

[James Tabor]

Hi!
The experiment failed. I already tested this last night. We allocate
in co_IntDoSendMessage and doing it again made things worse and the
system ran out of memory. ATM we are eating a lot of page pool and
that is why win32k kicks out before the stack is full, when inside a
message recursion. Still need to reposition IntCallWndProc/Ret when
calling the client.
Thanks,
James
PS. Good info!
