There is probably an anecdote from the Bell Labs from the early 1970s which either solves your problem or improves your understanding of it.

comment Understanding ulimit -u
This does not explain why Bash will not run a single process when you set the corresponding ulimit to something like 50.

comment How do you use apt-get to only install critical security updates on ubuntu?
Perhaps I'm stating the obvious, but if you are running a stable distribution, the only updates you get will be critical updates (mostly security, occasionally fixing crucial breakage in a package).

The problem is not the extraction, but the handling of multiple matches. For a single match, grab it with * ^Subject:.*\/60[0-9]+ and you will have the number in $MATCH.

comment Dynamic procmail filters
I don't really understand the follow-up question. You mean it should have a way to say "I don't know" and have Procmail fall through? Maybe add a condition to check that the value of FOLDER is not the empty string, * FOLDER ?? .

Is Procmail really necessary? I guess yes.

comment How to minimise SpamAssassin (spamd) memory use
As a middle ground, you could run a Bayesian filter as a first step, and fall back to SpamAssassin only for the messages for which the first filter did not come up with a clear verdict. Spammers tend to repeat themselves a lot so you could probably handle the vast majority of cases without SpamAssassin, but still have it available for new outbreaks etc.

comment procmail to deliver mail to 2 maildir locations
To deliver to a different server, change the action line to ! address@otherserver. This will add another Received: header and possibly change or add some other headers.
