O_APPEND is atomic for a single write. php_log_err uses stdio, so a
log entry longer than the stdio buffer size will cause non-atomic
writes.
Try this:
for x in A B; do php -r
'ini_set("error_log","/tmp/test.log");for($i=0;$i<10000;$i++)error_log(str_repeat("'$x'",5000));'
& done

Append is atomic and does not require locking.

Description:
------------
The internal php_log_err function does not lock the output file. This
causes long messages to get mixed together.
