I agree, with the caveat that the reactor threadpool size
adjustment api will need to be enhanced so that adbapi can
request more threads if the max connections is high, without
reducing threads if the max is low. suggestThreadPoolSize
is too crude to do that. Min threads probably needs to be
adjustable as well. Agreed?
