Hi,

Thanks for the info!

The worst case is 2MB * log_fifo_size(), but in an ordinary case where
only some data is being buffered, and the messages are smaller than
2MB messages, are 2MB buffers still being allocated?  To put it
differently, is a buffer of log_msg_size() always allocated for the
cached messages regardless of size, or only for the actual size of the
message?

How long until the next version? ;)
