    vos: Mark longjmp-used variables as 'volatile'
    
    vsprocs tries to do error recovery by calling longjmp from a signal
    handler. Although this is quite error-prone since we call a ton of
    non-async-signal-safe functions, make it a bit more likely to work by
    marking variables that are used after the longjmp as volatile. This
    reduces how often (depending on the platform) these values will be
    completely worthless after a longjmp since they were cached in a
    register or similar.
