Subject: [PATCH] unix/main: Check pending exception at the end of code block
 execution.

Usually this checking is done by VM on jump instructions, but for linear
sequences of instructions and builtin functions this won't happen. Particular
target of this change is long-running builtin functions like time.sleep().
