 Does that introduce a race condition?

In terms of multi-user operation, I think log files are only created
during locked operations, so not really.

In terms of system crashes: sort of. If the system crashes after the
file creation is committed to disk and before the chmod operation is
committed to disk, the log file should still be zero-length, and can
simply be deleted. On a completely asynchronous filesystem, data writes
might be committed to disk before the chmod is committed; I'm not sure
if that's worth worrying about.
