atomicity of formatted output?

[halcyonic@gmail.com]

Sorry, couldn't find this anywhere obvious in the documentation: are there any atomicity guarantees (even "best effort" ones) regarding formatted output from inside probes?  It looks to me like output from different probes is being intermingled occasionally, even if every probe only uses a single printf()...would it help to remove newlines in the printf()?

Thanks,
Nick
