You are correct I was thinking there was a major difference - dang - back to
the grind stone :-(

I thought it was too big a jump and it was :-(

I've been doing that all along (using gdb) but the backtraces don't seem to
show what is holding up the program closing. The final error from gdb is (as
best I recall late a night) a SIGINT due to a timeout waiting on a close while
it is trying to close the osg plugin but I will get the exact.
