Got it, it's not really related to threads, there was a bug in the
semaphore code that caused this, I've fixed it in CVS, it'll roll out
with the next release (1.20).
By the way, have you tried using the 'syswrite' option of the file
appender instead? It prevents overlapping messages as well and it's
easier to use than the synchronizing appender:
log4perl.appender.Logfile.syswrite = 1
