CreateRemoteThread and related stuff (patch)

Hi All,
I have been using spare time ro study a means to implement this api for
several
months in order to get my app (United Devices) to work but have been on
the usual steep learning curve for Win32/Posix C and how Wine interacts. In
looking at the wonderful work Alexander has submitted with this patch, I can
see this was at least a mile over my head but am gratified to know I was at
least exploring in the appropriate areas.
I have a question however, and by no means is this intended to be a critique
but
rather a newbie inquirey (I am too new to know what I don't know yet) and
am
very happy a developer was willing to take this on. :)
I am wondering why delete the CreateThread() code and refer all such
requests
to CreateRemoteThread()? It would appear to me that retaining the
CreateThread()
code in addition to and compliant with the patch changes would be more
expeditious
for apps that do not need a call for Remote Operations.
I ask this as I performed a cheap hack by copying the CreateThread() code to
CreateRemoteThread(), sprinkled a bunch of Fixme's thru out the appropriate
functions to see what info my app provided and what it may be looking for.
The app
actually worked quite well with the exception of spurious blocked threads
upon closing,
what a surprise :). Any help greatly appreciated and since I'm on the Left
Coast, I
can say "I'll be Back" to hopefully offer some production input.
Thanks, Roger
