You can delay the closing of a warp point however there are a few things that must be.

1) The warp point must be created.
2) The ship to close the warp point must be at that WP.

As long as that it true you can delay the close of the WP by simply ordering you WP closing ship to first move away then back then order close WP. Since your ship is at the WP your want to close, it will accept the orders.

Ex. The WP and your ship are at 5,5 your ship has 10 movements, then give the order move to 5,10 then move 5,5 then close WP.

This would give any fleet you have on the other side of the WP time to move and travel through before it was closed.
