Ack [~apurtell], will create a new Jira to track this.
Thanks [~bbeaudreault], tests are good. Looks like we can close this Jira (y)

> When a scan request comes in with a timeout specified and heartbeats/partials
> allowed, we calculate a time limit for running the scan to be half of that
> timeout. The idea is to return before the timeout expires.
> The calculation of that time limit is "now + timeout / 2", where now is the
> point at which the scan is starting to run. What's missed here is the scan
> may have spent upwards of a few seconds in the IPC queue before being
> serviced. In this case, the time limit may extend beyond the timeout of the
> request and the server will not return in time.
> We should calculate the time limit from ServerCall.getReceiveTime instead to
> avoid these timeouts.
