An excellent argument for maximizing the user of the pch.  With so many
recompilations, incremental overhead really adds up.

Unless you use non-released boost code, you're throttled by the boost
release frequency, which is on the order of once a month.  Would you avoid
putting files that change once a month into a pch?
