When soldier tries to walk through the door on 'gate' map the game freezes.
The ufoconsole.log contains a bunch of "CL_CheckDefault: Delaying event on entnum 39." messages.
If soldier walks to tile that is 2 tiles away from the door, door will open and everything is ok.
If soldier walks to tile that is 1 tile away from the door, door sometimes open and sometimes game hangs.
If soldier walks from the open door (1 or 2 tiles away) to some tile that is more than 3 tiles away from the door, door will try to close and game will hang.

I'm using Arch Linux x86_64 with dual core cpu.
