SERVER-10428 fassert on C runtime failures in Windows debug build
SERVER-8707 Sleep 10 seconds before entering ReplicaSetMonitorWatcher's loop

This restores the startup timing that was changed by commit
e3b8349ec305b00bdb7107f2d887549640a15c90, while preserving the
smaller time window within the loop between checking for
termination and calling ReplicaSetMonitor::checkAll().
Revert "SERVER-9518 Initialize user cache on process startup"

This reverts commit 5e9f82f54988c464e6925e48182b909b1b3fe115.
