Steps to reproduce:

* Create a datadir that is pruned
* Start with `-prune=550 -reindex-chainstate`
* Hangs with idle CPU

(`-reindex` works)
{
    StartShutdown();
}
static void HandleSIGHUP(int)
{
    LogInstance().m_reopen_file = true;
}
#else
static BOOL WINAPI consoleCtrlHandler(DWORD dwCtrlType)
