Hello again,
I've managed to make a backtrace of the threads that get run under
windows. As I said before, I don't really know what I'm doing with
gdb, but for backtraces and stepping through code.

What looks odd to me is the number of libpython3.11.dll instances I
get. As I understand there are a lot of changes to mingw's python.
So is this where the hangup is? I've tried to build a debug python,
but it failed out of the gate. (I suspect due to a new compiler.)
When I run with radioconda's python I get ...
# cat import_gr_thread_radioconda_run.txt
(base) C:\Users\chris>gdb --args c:\programdata\radioconda\python.exe

Something much more similar to linux. Appreciate any insights folks
have on what this all means.
Thanks in advance,
