You don't come across space-leaks in strict programs often because

Piping /dev/zero into a program that just sleeps does leak space,
though.
It only leaks 8K or whatever size your system buffers

Leak refers to a surprise.
I the meaning of leak is in a bit of flux. Originally, I believe it

But it can waste space (- space leak), for instance by
accumulating a big expression like
(..) - ((..)+1) - (((..) + 1) + 1) - etc.
instead of evaluating x+1 immediately
5 - 6- 7- etc.
So, it is called a space leak

Actually I think you can have a space leak without a time leak. For

So I just thought of something. If laziness leads to laziness leaks,
then is there such a thing as a strictness leak? I realized that the
answer is yes.
A lazy leak is a situation where I'm wasting resources to delay a
sequence of calculations instead of just doing them

imho they sound a bit spooky because it's not clear to me what the
situation without leak would be. (Time vs Space? Is an O(n) algorithm a
strictness leak compared to an O(log n) algorithm?)

True, but you can still have a time leak; this is particularily
relevant in
