For what its worth, the systems I'm testing this on are virtual machines,

That is almost certainly the cause; and I seriously doubt that there is anything that can be done either in your script or perl to alleviate it.

About the only thing that might offer a solution (besides dropping out of the VM) would be to try a different VM.

When I played with VMs a couple of years ago I had less problems with MS Virtual PC than Oracle's Virtual Box; but both gave me problems -- mostly with networking for the stuff I was doing. However, both have seen significant updates since, so my information is out of date.

FWIW: one of my customers uses VMWare and they are very happy with it; but they can afford to employ expertise and pay for support contracts.

Anyone got any experience of this phone's predecessor?
