Is Ruby commonly used in high-performance applications?

[Tuna-Fish]

Ruby is used plenty in the kind of situations where the performance of the program itself is less important that the overhead of IO. This should help quite a lot on such loads.

Dunno, but being able to do nonblocking file io could still be useful, I suppose.

[Asmod4n]

its definitely better than just having select in the base installation.
