If you drop the local gunzip method utility, you'll have to touch this.

Nitpick: you could avoid the strings concatenation operation with:

self.exec_command_and_wait_for_pattern(('cat /sys/devices/virtual/'
                                        'thermal/thermal_zone0/temp'),
                                       '25178')
