Coda File System

Red zone, stalling writer

I've had a few repeats of an issue while testing coda lately.
I'm getting into a situation where the following message is repeated every 
Red zone, stalling writer ( 11:36:41 )

Having a quick look at the code (coda-src/venus/ line 572), this could 
be due to the last case regarding a dirty cache.

	redzone = !free_fsos ||
		  free_mles <= MaxWorkers ||
		  free_blocks <= (CacheBlocks >> 4); /* ~94% cache dirty */

I'm adding and deleting a large number of temporary files in order to run some 
benchmarks on the filesystem so I guess this could cause the cache to become 

Once I get into this situation, it doesn't seem easy to get out of without 
killing the client and server :-(
Does this sound normal ? Is there anything I could do to mitigate the effects 
of this ?
