Not even with it actually.

Set up a test environment with > about 30-50 logins/second and I'm sure you can reproduce it. ;) Not even with 1100 logins/sec. :) And in the code I'm already catching EINTR. Only if listen() fails 10 times with EINTR it exits with that error. And between those 10 listen() calls is a 1 second sleep. But of course if the process is getting signals all the time the sleep also fails with EINTR. But a single HUP signal shouldn't interrupt more than a single syscall, so I've really no idea what's happening.
