gedit will take too long to start when running with eraser
Jun:
I found the gedit still works, but it just took TOO long. To speed up, you can first comment out the fprintf in e_queue_enque(). Then you run with gedit. After about 30s, the gedit window will pop up. And after another 30s, the gedit is fully loaded and ready to use.
This indicates that the current eraser setup will lead to very bad performance for gedit. The current setup is: one eraser thread per process and a fix-sized FIFO queue that can mostly hold 1024 buffers to be free'd.
Should offer a compiler option which hide all outputs during runtime
Outputs of eraser to stdout will fail a SPEC run, because SPEC will compare the output of a benchmark program with the ground truth.
