Console 'lag'?

So we've got our test FreeBSD 9.2-RC3 amd64 system running under Xen Server 
6.2 - with the xen 'guest' tools enabled (i.e. Xen Server can see it can 
suspend / resume the guest etc.)

We've noticed the console under XenCenter 'lags' sometimes - or, more 
accurately it doesn't update until you hit a key.

Best example is:

root at v1:~ #echo "Hello World!"
Hello World!

You *sometimes* don't get the prompt back, until you press a key. Other 
examples would be running 'ps ax' - nothing appears to happen - again, 
until you press another key.

This is only a cosmetic annoyance - just wondered if it was a known issue / 
any fix for it?
