Hey,

I think this error is caused by setting:
--8<---------------cut here---------------start------------->8---
;; STORE's socket is O_NONBLOCK but since we're
;; not in a fiber, disable Fiber's handlers.
(current-read-waiter #f)
(current-write-waiter #f)
--8<---------------cut here---------------end--------------->8---
where it should be:
--8<---------------cut here---------------start------------->8---
;; STORE's socket is O_NONBLOCK but since we're
;; not in a fiber, disable Fiber's handlers.
(current-read-waiter
(lambda (port)
(port-poll port "r")))
(current-write-waiter
(lambda (port)
(port-poll port "w")))
--8<---------------cut here---------------end--------------->8---
then this should also be done in "fetch-inputs" that is using non
blocking ports outside of Fibers.
However, I still have the following error:
--8<---------------cut here---------------start------------->8---

that originates from "valid-path?" in "restart-builds", not sure how to
fix it yet.
Thanks,
