I was trying to move some Scrubs xvid from my laptop to my large screen computer using samba. I first tried gnomevfs but it was too slow : it was painfully reaching 1MiB/s using 100% CPU which is not right when moving 4.4GiB. I know i could directly use cifs instead but i switched to smbnetfs (FUSE Samba browser) which can reach easily 10MiB/s (~physical limit, i think smbnetfs has 10% overhead compared to a manual mount). smbnetfs is usually fine but using it with nautilus is the WORST idea i had since a long time. File copy did not work because nautilus claimed there was no space on device. I was about to quit but i wanted to also delete some files. I clicked 'move to trash' ... worst thing ever : my computer got instantly locked. I don't know who (gnomevfs, nautilus or fuse) started a fork bomb or a syscall storm but it was quite effective. I couldn't even log in on a tty. It's the first time since i use GNU/Linux that i lock my computer that hard. Hard reboot and data loss.
