The story is ...

Apparently I fouled up when adding a remote ioctl facility. The foulup
caused timeouts in the keepalive under all circumstances. But that only
had an effect when the async flag "-a" was thrown into the mix. And I
accidentally left the async flag on in the 2.4.27 Makefile.

I _appear_ to have fixed the original foulup, and have uploaded a
fixed 2.4.27pre1. It even appears to work in -a mode again (client
flag).
