when opening (existing) files from Terminal.app using the `mate` command, it occasionally (but not always) takes a fairly long time (more than 5secs) to open the file in TextMate. TM in all these instances is already running, but doesn't necessarily have any open windows.

This is for small files (e.g. 30 short lines of code), so it cannot be the file size making a difference. If I open the files directly through TM's File -> Open... menu, no such delay happens.

During such a delay, if I click on the already running TM in the dock to activate it, the desired document that `mate` is trying to open immediately appears.

I also have this problem, consistently. It started about when I upgraded to High Sierra. 

My TM always has already-open windows. I also found that in general, switching apps (even to apps other than TextMate) sometimes triggers it to finish.

Initially I thought it might be related to the problem with slow Finder updates in the presence of sync apps (see e.g. https://apple.stackexchange.com/questions/264463/capturing-screenshots-on-macos-sierra-is-very-slow https://apple.stackexchange.com/questions/300633/screenshot-taking-a-very-long-time-to-appear-on-desktop ) but I haven't gotten around to testing that theory.

This actually sounds exactly like the problem I was trying to address with this PR. I'm glad someone else is experiencing it! 

For myself, I agree with the comments in that PR that a bring-to-front of all of TextMate would be undesirable.
