It hasn't exactly been the slowing down that gets me, though that 
can be irritating. It's usually the systems with multiple 
interactive subsystems that don't quite have their WSE's properly 
set that cause confusion.
If two subsystems are started in sequence without a delay that 
guarantees the first completely finishes allocations before the 
second is started, and if the two are capable of allocating some of 
the same devices, then there's no way to predict which subsystem 
will get the common devices.
Allocation happens in some sequence. The first SBS gets a few 
devices down its list while the second STRSBS command is being 
executed. Then the second SBS starts running through its list, a 
little behind the first but now running concurrently.
You can see the allocations jumping between them if you watch. IIRC, 
the last SBS allocation that gets run for a device determines which 
SBS gets the device.
