this doesn't address the behavior I observed on my test but I can see that this is worth doing still

it seems the waits I was experiencing is when the autofs request had failed..the request is deallocated, and then autofs retries the request according to an_retries

the following patch: https://reviews.freebsd.org/D58691 seems to address the waits I observed
