Subject: Re: [erlang-questions] OTP-10984
It was a while ago so I don't remember the exact details, but I think that
in order to recreate the bug you have to do many many smallish (10-20 bytes)
writes to a file with a small (1-2 ms) delayed_write timer. You can
theoretically also get unlucky with larger delayed_write values, but I have
yet to see that actually happen.
Also fyi this race was introduced in the R15B release of Erlang/OTP.

The release notes for Erlang R16B01 have the following fix:
OTP-10984 Fixed a race condition when using delayed_write when writing
to a file which would cause the same data to be written
Can anyone please describe under what circumstances the above race condition
will occur when using delayed_write?
