It is necessary to understand the impact of io-threads and what kind of races it can introduce. io-threads only puts read/write and related calls to a seperate thread.

This is not exactly how things are done. storage/posix allocates read buffers. but freeing is done according to refs() and unref()s done by various translators. this is necessary to hold the buffer persistantly in memory by read-ahead io-cache io-threads etc. There are some thoughts about bringing in more stricter rules about allocation and freeing within the code base. Like, all data structures, including data buffers are in a pool of preallocated lists, which are used/unused dynamically. This gives a more predictable memory footprint, but has other impact. avati
