Much thanks to you Martin, Heiko, and Danny. This version
ntp-4.2.0b at 1.1436mbg-xmas-o-win32-setup.exe works very well. The random
service hangs in some circumstances as autokey+sysstats seem to be gone.

Could super-fast slewing also work on other platforms without leap
insertion support?

I still have a problem: When the Windows NTP service on
is configured as an Autokey server with a trusted certificate, and a
Linux ntp-dev-20051208 client tries to open an unicast
client mode association. The Autokey Foxtrot begins, but will be
perturbated by many event log messages like this:

| sendto( (fd=216): No error
| sendto( (fd=216): Une opération d'entrée/sortie avec chevauchement est en cours d'exécution.

This may mean something as "overlapping I/O". On the Linux client side,
the association stays unreachable, and cryptostats show:

| 53727 83262.562 newpeer 44981
| 53727 83282.642 ntpkey_RSAkey_Client.3342971955 mod 512
| 53727 83282.647 ntpkey_RSA-MD5cert_Client.3342971955 0x0 len 311
| 53727 83283.462 refresh ts 0
| 53727 83284.465 flags 0x800e3 host Server signature md5WithRSAEncryption
| 53727 83478.512 update ts 3344368278

The dance is locked on this step for hours. The same problem already
happened with previous versions of Windows NTP, at least
ntp-4.2.0b at 20051016-1.1417-o-win32 and ntp-dev-4.2.0b-20051105-nt.zip.
