Eventspaces and User Breaks

Parameters that control user-level interruptions in Scheme code are discussed in MzScheme Reference Manual. The procedure wx:check-for-break can be used as a break-polling procedure that checks for Shift-Ctl-C. When wx:check-for-break is called, it only searchs for user breaks within the event queue of the current eventspace (as determined by the wx:current-eventspace parameter).
