Well, there's a quote for the ages!
Although multi-tasking did work well on my Coco, I soon learned not to  start 
two procs that both had to access the hard drive -- they spent most of  their 
time undoing each other's seeks.
 
To make a real OS-9 computer, Tandy should have put in a decent interrupt  
handler, but that would have cost another big Moto chip.  Certainly when  they 
went to the Coco 3 and added the GIME, with its additional interrupt  sources, 
it would have been nice to separate out the clock interrupts from  everything 
else.
 
Coco OS-9 had more funny bugs and misfeatures and wasted time with  
interrupts than anything else, IMHO.  --Mike K.
