details on frostwire-desktop repo ([PR #376](https://github.com/frostwire/frostwire-desktop/pull/376))
for now these debug traces are serving an indispensable purpose - i have each of them listed and monitored in a profiling script and they will all be removed when the feature is complete - if i remove them now i will only put them back in immediately and would need to repeat this for each commit - this feature s still incomplete and i do not expect this PR to me merged yet - i wanted to put this feature out now before it is completed only so that you guys can test it out and let me know when you consider it complete - i will then remove all of these in one go
