You seriously recommend to run a dedicated gpg-agent instance for each
of dozens if not hundreds of mail service users? You have to consider
that these gpg-agent services are meant to persistent beyond the initial
data processing call. Compared with my current single-agent approach
with task-queuing not really resource-efficient, is it?
