TODO
====

23WW48
. Add calls-per-minute to db access stats
. Find out why start-server calls are taking 250ms and fix
. Allow two or three servers to run for any given db
. Update avg call count/sec every 30 sec in no-sync
. get server uses no-sync process info to decide which server to suggest
. Use process table to decide who will do sync back
. Fix metadat being synced over and over

23WW47
. Finding server
.. look at .servinfo for likely prime main
.. ask the .servinfo prime main for real prime main
.. save prime main (for how long, 10 seconds or 10 minutes?)

. Starting prime main
.. get servinfo files - START
.. no files? create my servinfo file, goto START
.. have files? am I the prime main according to servinfo files?
.. no, I'm not the prime main, ping prime main
.. ping is good, prime main exists, register self as server if on same host as prime main DONE
.. no pirng response, remove the .servinfo file - goto START
.. if I am prime main according to .servinfo files, register directly in no-sync

. Starting non-main
.. get servinfo files
.. no files? launch server for main.db
.. have files? pick out prime main
.. register self as server with prime main

23WW46 - v1.80 branch
. Use file semaphore to kill tests, eliminate db load of the KILLREQ query
. Merge this change to revolution branch
23WW45 - the revolution branch
. Add "fast" db start option (no handshaking over NFS)
. Add server-ro to server types (just "server" is fine for read/write).
. [DONE] Create pause-server and resume-server calls
. Create rsync or cp sync to MTRAH function
. Change rmt:send-receive to divert calls to read-only server when possible
. [DONE] Change start server to call main.db server for 1..N.db servers, block until server is read for use.

23WW21
. Dashboard needs its own cache db in /tmp

23WW07
. Remove use of *dbstruct-dbs*

WW15
