Fernando does this already.  He also sends out e-mail saying he is off 
line for a bit (he is down the hall from me which is an advantage). 
Other maintainers do not, sigh!  More of a concern is that repeated 
pings often result in radio silence.

I don't think having a global maintainer step in after N weeks will 
really help.  It just butters over what may be a more serious underlying 
problem.
