"Michael Hudson Trace", heh heh.
Judging by the presence of spawn_layer_in_subprocess and the general
appearance of the stacks to be that of waiting on stdio, I'd suggest
that this process is just waiting for communications from the subprocess?

Only for the main thread - remember to do 'thread apply all backtrace'
(or 'thr a a bt').
In gdb, pystack and pystackv never completed (they hung too).
I've never got these to work, either. I'd be interested to know if they
ever work.
They work with a debug build of 2.5 or a release build of 2.4, but they
won't work with a release build of 2.5[1]. This is why I wrote the
backtrace.py tool!

[1] IIRC too much code gets inlined for the macros to find a particular
function by address comparisons of other functions. Or something
like that.
