batchqueue

queue data for an async write but do no parallel writes.

example

say, with leveldb we might want this.

var queue =
  require('batchqueue')
    (function (batch, cb) {
      //there is a chance to add something to the batch here.
      db.batch(batch, cb)
    })

//queue foo to be written
queue({key: foo, value: blah, type: 'put'})

batchqueue only ever processes one batch at a time, so you know for sure that writes are ordered as you expect.
