Dropped netlink updates during scans

We’re using BIRD to redistribute routes that are programmed into the Linux
kernel for routing to local containers or VMs. We set a scan time in the
kernel section of the config in order to notice when routes are removed.
Normally, BIRD picks up routes that are added extremely quickly. However,
if a route is added during a scan, it seems to be missed and it is not
picked up until the next scan, many seconds later.
Is this a known issue; is there a workaround? For example, is there a way
to tell BIRD that a route was removed from my external code rather than
having it poll?
