Windows 7 64 bits, Qt 4.8.1, with Arduino MEGA 2560 boards (3 tested) connected via virtual port com (Arduino driver)
Description
CPU usage goes to 100% when reading from serial port with signal/slot (only reading).
Sometimes reading second packet clears the situation for a while.
It seems to be due to the event loop.
Attached a simple code which reproduce the issue.
Works fine on Mac 10.7 with Qt4.8.1.
