Re: Leak in BASH "named" file descriptors?

Yes, thanks, that part I figured out many lines of code ago ;-) 

Chet answer earlier today kind of closed the loop on my "observations".  By design, as soon as you work with FD by varname you have to do all the housekeeping (regardless on how you create them).  But, depending on how you use regular "numbered" FD, it's not always the case (easy to see in all the examples I sent).

Of course, if you don't close (or reuse) your descriptors you will run
out of them eventually.
