The synchros let you engage gears without grenading the whole box. Now that the gears are all meshed and doing turns for 40 MPH, your crankshaft is still spinning at idle. You need to bring your engine revs up to match what your transmission is doing or your clutch will have to do it for you, acting as a big, expensive brake pad.

Rev matching coming out of a glide can't take too long. Except for an emergency it should be pretty well planned- you've got your whole glide to think about it. Pick your re-engage speed before you decelerate to it and work to meet it: I'm decelerating pretty quickly through 40 so I have to get ready. I'm going to jump back in at 30 and I want to be in 3rd gear for a quick, strong pulse so I need to be at about 2500 RPM. And... go!
