[Chicken-hackers] [PATCH] * scheduler.scm: import chicken.condition for 'signal' used in ##sys#default-exception-handler

[megane]

Hi,

Kooda found a scheduler related segfault. There was an unimported symbol
in the scheduler.

This didn't cause any warnings as scheduler is not in a module.

I tested for additional missing symbols by wrapping it in a module, and
there shouldn't be any.
