Public bug reported:
The trace-cmd in ubuntu ( 1.0.3-0ubuntu2 on saucy 3.11.0-4-generic ) gives
'interrupted system call' errors on the
example uses I could find.
Note that this also happens with the trace-cmd from Eric Miao's ppa referenced
in bug 1068464,
but it all works fine if I build from current trace-cmd git
