Description:
In the case where 
#if defined(HAVE_PREAD) && !defined(HAVE_BROKEN_PREAD)
is true, the code in SerialLogFile::write() is missing an fsync.

How to repeat:
Kelly Long found this in the code.  I don't know which OS uses this.

Suggested fix:
Move if (forceFsync) fsync(handle); outside the #endif
