Implement read throttling when writes backlog
...
Reject operations in such a case with LDAP_BUSY. If read_event feature
is on, just stop reading from the connection. However this could still
result in deadlocks in reasonable situations. Need to figure out better
ways to make it safe and still protect ourselves.

Epoch based memory reclamation
...
Similar to the algorithm presented in
https://www.cl.cam.ac.uk/techreports/UCAM-CL-TR-579.pdf
Not completely lock-free at the moment. Also the problems with epoch
based memory reclamation are still present - a thread actively observing
an epoch getting stuck will prevent LloadConnections and LloadOperations
being freed, potentially running out of memory.
