is it possible to have a process substitution with both input and output
redirection? So far I use the following work-around
cat parentprocess.sh:
#!/bin/bash
mkfifo fifo 2/dev/null
exec 5 (./subprocess.sh fifo)
exec 6 (cat fifo)
I think

Cool. Is there any hint/doc/faq/how-to implement old behaviour, i.e. wait
until all children of current bash process will exit?
I imagine a loop on wait until it returns because there are no unwaited-for
children. You can detect the interrupted exit status and behave
accordingly.
I'll
Use the attached patch and rebuild configure using `autoconf'.
