The original problem is the current sh ptest-runner blocks indefinitely
when a package ptest blocks (we don't control this), now python-ptest is
blocking the ptest-runner, see [1]. The way to solve this is adding
timeout in some place.

I know that bash support timeout option but this option works over the
whole process making us to define timeouts too big or per machine/device
also tiny systems mainly don't use bash. That's the reason for i decide
to write python version of ptest-runner that applies a timeout over the
output of the program give us better control/granularity over the
running ptest.


If you now other way to solve the problem please tell us.
