Comment (by ryandesign):

 For an approximate timeframe, the original code was
 [https://github.com/libuv/libuv/commit/74999f8f9974970e4d71a0df521e178e3149f3df
 added on 2012-10-01] with the comment `Serialize writes on OS X,
 concurrent pwrite() calls result in data loss` and
 [https://github.com/libuv/libuv/commit/cb03e3bd26587b851552ad8b54b30600e48ef829
 a fixup committed on 2012-10-09] changed the comment to `Serialize writes
 on OS X, concurrent write() and pwrite() calls result in data loss`. There
 is a mention of a nodejs test, test/simple/test-fs-sir-writes-alot.js,
 that this fixed; if we could find that test and figure out how to run it,
 we could test it on various systems to see which ones are affected. OS X
 10.8 Mountain Lion was the current version at that time.
