The engine names the filesystem a waiting folder is on; a warrant is recorded for that filesystem, and a
folder on another is asked about again and not taken there meanwhile. Entries the engine could not take
out while their disk was away, stated before a send, do not hold that delivery's gate. mesh-host pinned
to d2d9fbbd.
A module's containers that declare identity run as an identity the controller allocates once, mesh-wide,
from 50000-59999; each access names its users and whether its folder is taken; an access wait is excused
for a folder the mesh may not keep yet, and the operator is asked once per folder and machine, the folder
taken only on the warrant. All of it is sent only to an engine at contract 5. A placement for an access a
newer build brings is judged against that build (issue 575). mesh-host pinned to the ADR 0325 branch head.
