+synopsis: Interrupting builds in the REPL works more than once
+cls: 1097
+---
+
+Builds in the REPL can be interrupted by pressing Ctrl+C.
+Previously, this only worked once per REPL session; further attempts would be ignored.
+This issue is now fixed, so that builds can be canceled consistently.
