So, you get a 100 Continue" immediately and curl just sits waiting for 60
seconds before it proceeds to actually send the data?

The reason for this can't be much else than a curl bug as I see it.

Perhaps. Why are you enforcing chunked encoding at all?

Would you be able to fire up a debugger to run this command line to see what
some internals think?

I don't think we've changed anything in those parts since that release, but it
would certainly feel safer if you could try 7.10.8 and see if the problems
remain before we start to put any more efforts into debugging this.
