Yes.

Interesting. I'll keep that in mind, will be helpful for me later.

In general I get your point, which is valid. Perhaps I am doing a very
corner case. A script is checking some stuff (mostly versioning checks
form web). In case it was already run automatically, it adds a delay
before running the checks. If the user decides to run it right away, the
old script and therefore the delay gets terminated and the checks
immediately being.
