18826	wp_maintenance() expiration time needs to be filterable	jaredh123		".maintenance files expire after 10 minutes if something goes wrong.  10 minutes is a long time, when most upgrading operations are attempted and fail within 20-60 seconds.

I propose three things:

1. changing the default expiration to 5 minutes (300 seconds)
2. Adding a filter to allow plugins and themes to filter this time to increase/decrease it
3. Also, while I was in there, it seems prudent to attempt to delete the file if it has expired.  The only argument I could see against this is that possibly it might be expensive if the file can not be deleted and wp attempts to delete the file on every page load.  So I can take or leave 3 (and 2), but #2 I think is really important."	enhancement	new	normal	Awaiting Review	Upgrade/Install	3.3	normal		2nd-opinion
