[CentOS] help with a dd bug

Hi,

Can somebody reproduce this bug?
http://bugs.centos.org/view.php?id=4220

dd if=/dev/zero of=/dev/my_usb_stick_device_name bs=4096 count=10000
can not be stopped with ctrl-c and is not responding to signals

(count=10000 can be modified to give you enough time to test)

The bug has been closed with the following comment:
"As said: dd is in an uninteruptable state when you do that. This is not a bug"
This is wrong, because IMHO dd should receive the signal after it
finishes the current read()/write() and returns to user space, but
this is not happening.
How can I reopen the bug?

Thanks

Adrian Buciuman
