As you suspect, the problem is with this part of the function. It doesn't
really have anything to do with PROMPT_COMMAND, though. You must be
exporting the function so your PROMPT_COMMAND will work in interactive
subshells, and the problem is there.
Aha, indeed I have this too:
export -f foo
Removing it and the error goes away on successive subshells. :-)
I already export PROMPT_COMMAND=foo. Maybe I don't need to try and
re-export the function every time also?
bash: foo: line 39: syntax error near unexpected token `('
bash: foo: line 39: ` done <<(jobs);'
bash: error importing function definition for `foo'
Am I missing a finer point of redirection from a substituted process? Or is
something different in bash 3 that I need to work around here?
One of the bugs fixed between bash-3.1 and bash-3.2 concerned formatting
problems with redirections and process substitution -- the construct you
used. That code is used to decompose functions to pass them through the
environment, and the incorrectly-formed function has a syntax error that
prevents it being imported by the subshell.

Thanks Chet! I'll chalk this up as an old bug already fixed.
