Mark Salyzyn 71919f4f5d liblogcat: measure performance ... Existing dummy benchmark converted to a single-pass benchmark. Add support for ">[filename]" interpretation in liblogcat, helpful to provide more consistent benchmark results when sending output to /dev/null. NB: results are not consistent as there is a roundtrip to logd service, but they are indicative of better performance for liblogcat.
