in thread Perl graphics engine?

The performance of the library itself will be comparable, yes. But if you want to do some more involved calculations (say e.g. precise collision detection) in Perl, it may slow down the program substantially. Perl is just not meant for that. But we are lucky in the way that Perl allows for Modules written in C and even writing single subroutines in C or C++ quite painlessly via Inline::C(++).

[tye]: I don't know if you can just dismount, but I thought so.
[davido]: yeah, umount -f isn't powerful enough.
[tye]: probably something in the init subsystem that does the mounting that you could disable and reboot.
davido needs to close laptop to board flight home from yapc.
[davido]: I'll look into it in a few hours probably.
[davido]: when i do get to that point I think I'll do it in a vm snapshot just in case. :)
[oiskuu]: tye, you were right: loginuid/sessionid are part of task struct if compiled with AUDITSYSCALL. I have some doubts if you should actually depend on that feature.
[Corion]: oiskuu: Depends on what you want to do with that information
[tye]: I'm not depending on that feature. But I could in this environment. I'm using getlogin(). shrug
[Corion]: For benign logging (which user started this DB instance), it's OK
