The important point is that the current thread, which intends to block on an
event loop mutex, drops the DatabaseAccess recursive mutex before. Any other
thread may acquire the DatabaseAccess mutex at will. It seems that the
unlocking does not work though - apparently, the mutex is locked. It's a
special case of a Solid event delivered during the startup phase.
What we should reconsider is the dependence of CollectionManager on
DatabaseAccess as a "big lock", which adds this complexity.
