I have noticed that qemu hangs when I launch it. from what I can
tell, it seems to be based on the reading of disk images: Here's a
sample taken from the PowerPC build:
Sampling process 12004 for 3 seconds with 1 millisecond of run time
between samples
Sampling completed, processing symbols...
Analysis of sampling qemu-system-ppc (pid 12004) every 1 millisecond
