I agree that something like the patch (i.e., introduction of promotion
from cancel request to terminate one) is necessary for the fix. One concern
on the patch is that the cancel request can be promoted to the terminate one
even when secure_write() doesn't actually get stuck. Is this acceptable?
Maybe I'm tempted to set up the duration until the promotion happens....
Or we should introduce the dedicated timer for communication on the socket?
