Rm_client is derived from Pager_object. If the Pager_object is also derived from Thread_base (which is the case for NOVA) then the Rm_client object must be destructed without holding the rm_session_object lock. The native platform specific Thread_base implementation has to take care that all in-flight page handling requests are finished before destruction. On NOVA it is done by doing an IPC to the pager thread. (performed in Pager_object::dissolve() in base-nova). The called thread than executes its operation until end which also requires in some cases to take the rm_session_object lock. Since _client_slab insertion/deletion also must be performed synchronized but can't be protected by the rm_session_object lock because of the described dead_lock situation, we have to use a synchronized allocator object to perform insertion and deletion of Rm_clients.
