Actually this wouldn't surprise me.
When the axle lets go, my bet would be that the top of the tire gets up against the body.
In my car if the tire leans in toward the center, the top of the tire would quickly come into contact with the seat bucket. This would most likely have two effects: The tire would act as though its brake was applied, and second, it would not lean any further. In my car the angle of lean would be very slight since the tire occasionally contacts the body at that point under full deflection... Other car bodies may be different.
That axle failure is not unusual on Jags - probably more common than the u-joint failure. Glad you only had a "Maalox moment" and did not accrue any personal damage
CWI
http://www.cwiinc.com/index.html sells HD parts for those axles that help a lot.
BTW, Mustang-type IRSs suffer from similar weaknesses, so drag racers tend to go for the live axles instead, and even those occasionally break. A stick shift with repetitive very hard launches at a drag strip using slicks is not a good application for an IRS.

Tom
