Yes, but given Matthew's code, it first waits (i.e., blocks) with `sync'
until a client tries to connect (but does not `accept' it yet).
Then it goes to atomic (i.e., somewhat non-interruptible) mode and before
accepting the client, it checks again that the client is still there.
For this last part

I'm not familiar with `sync/timeout' or `scheme_fd_to_semaphore', but
from `sync/timeout's documentation:
"A zero value for timeout is equivalent t
Thanks for you answer Diogo, it actually made me think that I could use
`sync/timeout' instead of trying to poll directly:
(sync/timeout 0 (scheme_fd_to_semaphore s MZFD_CREATE_READ #t))
Unfortunately this does not work :)
It always returns #f.
I tried with MZFD_CHECK_READ instead, but got a segfa

Writing more about how to deal with the unix domain socket blocking,
this is how I do it: I make an input
It works, thank you very much!
(I guess the first two `lambda's should be removed, since
parameterize-break takes bodys and not exprs).
Now I just need to figure out how to do the double check, and I'm done.

Use
(define MZFD_CREATE_READ 1)
instead of MZFD_CHECK_READ.
An advantage of writing documentation is that it reminds me how the
function works.

No. That C function is merely
(define (call/enable-break f)
(parameterize-break #t (f)))
but in a more convenient form to call from C.

Is it possible to use scheme_call_enable_break [1] with a non-primitive
Racket procedure?
In particular, I'd like to use it with shawnpresser's unix domain socket
package [2] and its `accept' function, but I'm not sure how to make one
work with the other.
I cannot really use the example of tcp-co
