I already tried the fl_redraw_object() before posting the
message, and it had no effect. However I was not calling XFlush(), so
I will give that a try.

I use async in my grame front end, but in this case it would
add all kinds of complication to the process, and really isn't the way
it should be done, this is very much a "this needs to happen, then
this, with nothing inbetween. The fact the the UI locks up is fine
with me, as I would just be wrapping the callbacks with functions to
lock it anyway. I can do without the IO I want to happen, I just think
it might be nice to tell the user the progress.
