Re: data written to file missed by reader

Also, be sure that you don't have multiple threads or processes sharing

That's not true if one of two things is the case:

1) The file descriptor is protected by a mutex that is acquired before
a seek and released after the read/write, or

2) You only use operations with built-in seeks like pread/pwrite.
