A problem with google perftools is the `SIGPROF` signal used in sampling will interrupt polling such as used in ZeroMQ. Otherwise, it is a good tool in the toolbox.
- vectorEQ 7y agothat is/was a problem with zeroMQ, not gperftools: 27 SIGPROF terminate process profiling timer alarm (see setitimer(2)) its use is specifically what that signal is for. Additionally, it seems fixed in zeroMQ for some things already in 2016... so i doubt thats still valid issue.
