For some strange reason it doesn't seem to implement thread-sleep!. Is there a reason for this, and is there a more portable way to get a Scheme program to sleep for a specific amount of time?

Racket isn't a Scheme anymore in any real sense anymore as far as I'm concerned, they've changed the name for a reason. I'm porting my Racket code to a "practical" superset of R5RS to run eventually at least in Chicken and aiming for a R7RS-big app when that will happen, and I have to say the process isn't easy...
What does this do? #lang r5rs
(#%require (lib "srfi/1")) ; SRFI-1
(display (delete-duplicates '(1 2 3 3 4)))
Answer: [spoiler]Error: "null-list?: argument out of domain {1 2 3 3 4}" because '(1 2 3 4 5) is made out of some kind of [b]mcons[b] chain instead of cons.
The solution: substitute "srfi/1" with "srfi/%3a1"(wat...), which prints the expected (1 2 3 4). [/spoiler]
I was at my friend's apartment smoking hookah with him and some people I didn't know. For some reason they would all chew and lick the hose instead of just using it to smoke and it was really irritating.

why are some cold and warm front bumps shown to be on one side on the same string and then on the other side on the second half of the string?
