> Currently the logging subsystem depends on the pn_string_t class to manage the messages that it sends out. This means that it is subject heap allocations at unknown time with unknown amounts.
> Given that a logging subsystem should always succeed and take as little time as possible, it would be much better to avoid any allocations at all, but at eliminating as many as possible will be a significant improvement.
