 Working notes. In the commit
    * Fixed a whole cluster of errors that could happen when a savegame was sufficiently large and some background threads were getting double-run.

 The concept of IsCurrentlyWaitingOnThread was added to a number of threads, where the variable to be used to implement a "Only one thread at a time in this critical region" restriction

    public override void Execute()
         {
....
+ if ( IsCurrentlyWaitingOnThread > 0 )
+ return;
...
+ Interlocked.Exchange( ref IsCurrentlyWaitingOnThread, 1 );
<critical region>
+ Interlocked.Exchange( ref IsCurrentlyWaitingOnThread, 0 );

It looks like this is intended to say "When I enter this function, if another thread is doing critical stuff, I should retirm"

Two things I'm concerned about.
First, the check
+ if ( IsCurrentlyWaitingOnThread > 0 )
+ return;
was only added to a couple of the threads. It's missing from a bunch of the other threads changed in that commit, like MovementPlanning and Tachyon Planning. I'm not sure if this was an oversight or there was some reason for it I'm missing.

Second, it seems to me like there's a (potentially very small) race condition where multiple threads threads could successfully pass the if ( IsCurrentlyWaitingOnThread > 0 ) check before any of them gets a chance to call Interlocked.Exchange( ref IsCurrentlyWaitingOnThread, 1 );

I think the calls to
Interlocked.Exchange( ref IsCurrentlyWaitingOnThread, 1 );
need to be
if ( Interlocked.Exchange( ref IsCurrentlyWaitingOnThread, 1 ) != 0 )
    return;
because Exchange returns the previous value in IsCurrentlyWaitingOnThreads
