11 seconds for application startup. That's gdb's cpu time. Application
has 0 seconds of run time. Later some steps take 2 seconds, but some
steps are interactive. The unusual thing is that my application freezes
for those 2 seconds and then does the rest very quickly. That's without
any breakpoints, just running it in debugger.

I have no clue what are above three tools, but stepi is interactive. At
least I didn't bother to find the point where those 2 seconds are spent.

System native mutexes, I guess.
