Description 
See this Comm Center thread by Dick Berg and this one by Stacy Mills. The dome controllers aren't responding well to being told to close while opening. The requirements for this in dome/roof controllers are squishy enough that I will simply avoid the condition.

  Fix both startup and shutdown in unsafe weather. They are OK.

            Prevent weather safety interrupts while opening and closing the dome from within the Scheduler. GEM:1699

Not all of the below are related, but two are. Two problems: In both cases checking for  unsafe weather and returning false if so was a big mistake. Startup and shutdown in unsafe weather is just fine.






PS Where are the commits for changes on 16-June?

REOPENED






Show-stopper problems here. Still investigating.

Disable interrupts while opening and closing.






Check for weather unsafe after disabling weather safety. This will avoid the tiny race where it went unsafe between checking it and disabling it.






[edit] The latter was a very bad idea.
