It shouldn't make much difference, though I've never benchmarked it.

That would cause a lot of work for smallish docids, as smallish numbers
are generally pretty common so this will be trying to delete a lot of
documents for every call to delete_document.

Perhaps this int/string overload in the PHP bindings is too much of a
"gotcha", since it's unusual to distinguish between a number and a
string of a number in PHP.  We could instead wrap the two different
forms of delete_document (and replace_document) under different names.

Use xapian-compact (or quartzcompact for quartz).  It merges the tables
at a low level, so it's pretty quick.
