Tried to strace this to see what happens, but seems to happen before even strace catches the first syscall or signals. The slow down is a a second a more, but like I said, don't see anything in the trace that would tell me from where is coming from. P.S. sorry for the poor explanation, but is really hard to say what exactly happens.
