Looking forward to meeting CCR Users at READY!

My other thought would be to (carefully!) take out and release the oddDEF lock for the class

//adjust timeout
lock +^oddDEF(class):5
//check $test and handle timeouts appropriately
write $test
1
//make sure this happens
lock -^oddDEF(class)#"I"

Would /multicompile=0 force the behavior you want?
