Actually, the pressure in a typical Xenon flash tube isn't all that low.
Perhaps 450 torr at room temp, close to atmospheric (760 torr) when hot.
What breaks it down is the trigger pulse of several kV. Self (i.e. not
externally triggered) breakdown on the larger tubes requires tens of kV.

And, the short arc xenon lamp (as used in projection lamps, etc.) is
actually under fairly high pressure (5-10 Atm) (which is why the hazard
from these lamps exploding)
