Pinholes caused by airbubbles are not completely white, they've got a black outer ring. This could be a relevant question in determining the cause of your pinholes.

If developer contains sodium carbonate, a strong acid stop bath will produce carbon dioxide, also pin holes. Use plain water rinse, then acid stop to preserve fixer.
I used to keep the older fixing bath as a rinse/stop bath. For paper though, I n oticed that using a stop bath helped keep clean whites.
