You avoid that by protecting your signal lines from ESD.  Pick a level 
of ESD protection suitable for the type of equipment you are making, 
design the hardware properly, and test somewhat above and beyond the 
requirements of the appropriate standard (not /too/ far above the 
requirements, of course - extra protection is costly).  ESD cannot cause 
a botched or partial reset as long as the equipment is used as designed.

You design the hardware so that this will not happen.  It is not hard to 
make a power supply that does not go up and down a few times on startup 
- it is even easier to make a decent reset circuit that only releases 
the microcontroller's reset after the power supply is stable.  If the 
chip has a built-in brown-out protection that is good enough for the 
job, use it - if not, make an external brown-out circuit.

(For the benefit of C programmers here who are not involved in 
electronics design, this argument is about undefined behaviour in 
electronics.  I am recommending that you make your electronics so that 
undefined behaviour does not happen, and that your inputs are sanitised 
before you use them - supercat apparently prefers to allow undefined 
behaviour to happen in various ways, and pretend that he can safely 
detect it and recover after it has happened.)

If you think your system is going to get a cluster of glitches at 
startup, that you cannot protect against using suitable hardware, and 
you think that a watchdog will make the system safe and reliable - 
please as someone else to design your hardware.
