[entropy.client.package.actions] fetch: avoid potential deadlocks
...
Holding shared locks on other downloadable files while holding an
exclusive lock on the file to be downloaded is looking for a disaster.
Try not to hold locks on other potentially downloadable files while
holding one already.

[entropy.db.sqlite] drop support for locking based on rwsem for memory repositories
...
Firstly, rwsem is semantically different from flock (but this was known) and
this may confuse the API consumer. Secondly, the locking infrastructure is
purely meant for inter-process synchronization, threads synchronization is
not a current use case.
