I hate filing these kinds of "bad stuff seems to happen frequently" kinds of bugs without specific STR, but while dogfooding when out and about tonight, I noticed the homescreen getting "stuck" quite a bit after I messed around with

An extreme case is bug 798700, but also at other times the homescreen would stop responding and the only way to get it back was to reboot the device.

I think this is one of the most severe dogfooding issues, since it won't be clear to users how to un-stuck the homescreen.
this seems a dupe of 798700. please re-open if that's not the case.

It might be splitting hairs, but in bug 798700 the homescreen locked up *and* was rendered as a blank white screen.

I also see other lockups that don't result in a misrendered homescreen, just an unresponsive one.  They're probably the same underlying issue, but I'd like to verify them separately in case there are two separate bad things happening.
Depends on: 798700

lock up and misrendering of the homescreen, followed by unresponsiveness, + a reboot tends to be OOM issue.

Can you check your logcat while you're doing these steps to repro please?

Based on what evidence?
having stated that... lessons learned on the need to dig deeper. ( bug 796773 )
Another way to diagnose possible OOMs is to open a terminal and run

$ watch -n 1 'adb shell b2g-procrank'

If you see the "USS" of one of the app processes go up near 100MB and then that process disappear from the process list (accompanied by some sort of visual crash in gaia), then you've almost certainly seen an OOM kill.
Oh sweet!  thanks for the tip!

There is not really something that I can reproduce.
And, it looks like in recent pvt build
b2g18 branch looks pretty fine as for now.

Please reopen this if it still happens.
