xctrace/instruments has big delay caused by dyld notifymonitor

Hello,

While using the App Launch template with xctrace, the launch time for my app is much longer than expected. While investigating, I saw 4 syscalls to mach_msg_trap from dyld that are causing a delay of 100-300ms:

I would like to know if there's any way to improve the performance here, as this is adding around 1 second more to my measurements and I have been trying to find a solution.

Thank you very much for your help!
