This is basically the same as before, it is even shorter. The
complaint was that I don't use a whole sentence in this error
detail. Won't the change fulfill the same complaint?

To be honest, I'd like to stick with your earlier proposal:

Singular:
Process holding the lock: A. Request queue: B

Plural:
Processes holding the lock: A, B. Request queue: C, D

This seems to be a good trade-off between project guidelines,
readability and parsability.

Best regards,
