Regression: investigate memory leak

[richthegeek]

Memory leak observed in dependant applications from no earlier than 3.1

Figure out which version to blame and investigate changes in that version.

[richthegeek]

Regression pinned to 3.3.0 (bd0cfcd): performance before is signifantly improved.

Line 159 in bd0cfcd

this.log.trace = this.log.trace.bind(this.log, {messageId: message.properties.messageId})

The bind here is recursive, so each job builds on the last.

Stripping out tracing, replacing it with debug, is a viable solution.
