the pysim code sometimes gets a floating point overflow error, possibly due to large timesteps on an overloaded machine.

this was fixed by disabling the wind drag correction code until we sort it out

GCS_MAVLink: protect against reentrant update
5ef817a 
GCS::update() shouldn't be reentrant but there may be places that make
it so: one of them is when we call hal.scheduler->delay(): this may
trigger  the callbacks registered to keep mavlink messages going when
sleeping for an extended period.

There's at least one callchain that is triggered by trying to test
motors on ArduCopter via a mavlink message:
