* The relations between threads, messages and participants can be described as

/**
* Collector class for read-ahead result objects. Mmdb may now try to fetch
* message/thread records before it's requested explicitly.
*
* The read ahead behavior can be controlled by an integer mozSettings entry
* "ril.sms.maxReadAheadEntries" as well as an integer holding preference
* "dom.sms.maxReadAheadEntries". The meanings are:
*
* positive: finite read-ahead entries,
* 0: don't read ahead unless explicitly requested, (default)
* negative: read ahead all IDs if possible.
*
* The order of ID filtering objects are now:
*
* [UnionResultsCollector]
* +-> [IntersectionResultsCollector]
* +-> IDsCollector
* +-> ResultsCollector
*
* ResultsCollector has basically similar behaviour with IDsCollector. When
* RC::squeeze() is called, either RC::drip() is called instantly if we have
* already fetched results available, or the request is kept and IC::squeeze()
* is called.
*
* When RC::collect is called by IC::drip, it proceeds to fetch the
* corresponding record given that collected ID is neither an error nor an end
* mark. After the message/thread record being fetched, ResultsCollector::drip
* is called if we have pending request. Anyway, RC::maybeSqueezeIdCollector is
* called to determine whether we need to call IC::squeeze again.
*
* RC::squeeze is called when nsICursorContinueCallback::handleContinue() is
* called. ResultsCollector::drip will call to
* nsIMobileMessageCursorCallback::notifyFoo.
*
* In summary, the major call paths are:
*
* RC::squeeze
* o-> RC::drip
* +-> RC::notifyCallback
* +-> nsIMobileMessageCursorCallback::notifyFoo
* +-> RC::maybeSqueezeIdCollector
* o-> IC::squeeze
* o-> IC::drip
* +-> RC::collect
* o-> RC::readAhead
* +-> RC::notifyResult
* o-> RC::drip ...
* +-> RC::maybeSqueezeIdCollector ...
* o-> RC::notifyResult ...
