The only part that should be running when not on wifi is the crash collection. We certainly *should* be running that when not on wifi; you don't get a second chance to run the kernel crash handler, and we want to know about crashes that only happen when not on wifi (including, possibly, crashes that happen /because/ you're not on wifi).

So the shell can't know that the process has died and move on until the crash handler has finished running. (The same is true on the desktop, it's just less impactful because the app is usually not full screen and blocking the UI at the time.) We have already taken steps to minimize the amount of processing done on the core file as part of the apport crash handler, in favor of post-processing the crash file from a queue. It's not clear what further optimization of the crash handler is possible.

It would just cause the app to hang longer in an unkillable, memory-consuming state. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apport in Ubuntu. https://bugs.launchpad.net/bugs/1278780 Title: apport takes too long to write crash report, appears to lock up phone Status in Apport crash detection/reporting: Confirmed Status in apport package in Ubuntu: Triaged Bug description: I can trigger a crash easily on my phone via bug 1262711. Other bugs are available. When that happens my phone appears to freeze. I am unable to do anything for approximately 1 to 1.5 minutes. As a user my initial gut reaction is to reboot the phone, thus losing the crash report, and wasting my time. Having the phone lock up for 1.5 minutes is a terrible user experience.
