In the case of the capacitor storing the energy for a flash, flash
discharges are actually rather finely timed. Something to the effect of
1 millisecond for a full-power flash, this discharges the capacitor
quickly, but not instantly. Lower power strobes only allow a partial
discharge at the same rate, which is why recycle time is much quicker
when using a flash at a lower power, because the cap isn't empty.
Shorting a capacitor without a resistor allows high amounts of current
to flow, which can cause an arc across the dielectric, thus destroying
the capacitor. At least that's how I understand it.
In other applications, discharge is much slower, such as when they are
used to smooth ripple current from a DC power supply.
