Greg Thomas commented on LBCORE-147:
------------------------------------

I don't believe speed would be an issue; you could spawn off a scavenging thread at the time you create a new log file; however it would use more resources, which could be an issue on embedded systems. Though that can be minimised by putting files in a single directory.
