    Description

      The time required to submit new HSM requests grows linearly with the size of the HSM actions log. This is because we first run hsm_find_compatible() on the HAL to see if there are already existing actions running or waiting on the files in the HAL. We should avoid this by keeping an in-memory such cache of actions indexed by FID.
