Do not sync to disk after each individual manual page (duh!),
only sync to disk one single time when all data is ready.
Rebuild times for /usr/share/man/mandoc.db shrink on my notebook:
In standard mode from 45 seconds to 11 seconds (75% reduction)
In -Q mode from 25 seconds to 3.1 seconds (87% reduction)
For comparison: makewhatis(8): 4.2 seconds
That is, in -Q mode, we are now *faster* than the existing makewhatis(8),
and careful profiling shows there is still a lot of room for improval.
