Re^6: Writing to a log file without colliding (Win32 >> race)

There is a race condition in append mode in Win32. Your test case must just not race fast enough / close enough. BTW, binmode reduces the window size for the race.

Indeed, you are correct. That's a shame, it would have been useful to me. Removing the delay and upping the line count to 10,000 eventually showed some corruption creeping in. With regard to the binmode, I was under the impression that ':raw' was equivalent to it. Especially inconjuction with syswrite? Examine what is said, not who speaks.
