Thanks Rex! I verified the revised patch against upstream.
debian/changelog should reference oneiric-proposed, not oneiric.
Additionally since the package uses a patch system that supports
comments, debian/patches/debian/gtk-fork.patch should be using DEP-3
comments which would clean up the changelog significantly. Since this
fix has been slow to get into the archive, I have made these changes and
uploaded to oneiric-proposed.
I was unable to reproduce the issue based on the test case. Could
someone affected by this update the test case accordingly? Unsubscribing
ubuntu-sponsors and subscribing ubuntu-sru and sru-verification.

Title:
gvim slow to respond
Status in “vim” package in Ubuntu:
Fix Released
Status in “vim” source package in Oneiric:
Confirmed
Status in “vim” package in Fedora:
Unknown
Bug description:
[Impact]
The bug makes gvim windows unresponsive to keyboard events for seconds to minutes after a window is opened. It happens every time a window is opened. It's annoying and makes gvim very difficult to use.
Problem: Opening a window before forking causes problems for GTK.
[Development Fix]
using patch from upstream v7-3-315.
> Fork first, create the window in the child and report back to the
> parent process whether it worked. If successful the parent exits,
> if unsuccessful the child exits and the parent continues in the
> terminal. (Tim Starling)
[Stable Fix]
Retrieve upstream patch v7-3-315, a few minor changes to fit into current codebase.
[Test Case]
1. Open a gvim window
2. Focus window and press arrow keys immediately after opening
Broken Behavior: Arrow keys have no effect. Clicking around will move the cursor normally
Fixed Behavior: Arrow keys move cursor
[Regression Potential]
N/A.
[Original Report]
Opening up GVIM takes long time and edit commands such as moving are very slow.
strace shows lots of waiting:
