FTDC can stall for a few reasons when the system is struggling, but this is just when it might be most helpful. Reasons include

out of tickets
cache is full and ftdc thread gets used to do evictions - the ignore_cache_size session option (~~WT-2932~~) might help here

We should arrange for FTDC not to get stalled by these conditions.
