Run this code on :
- Windows XP with OpenTTD 0.7.0. RC2 give this crash file
- Ubuntu Hardy 8.0.4 it just said "Segmentation fault"

History :
- Before using this kind of code, there are some one report on TransAI thread that it make the game slow.
- I decided to make such a task manager, and try to implement it in this way.
- When I run (start_ai) it give the crash.
- Ask this to forum : http://www.tt-forums.net/viewtopic.php?f=65&t=43746

I have no idea whats wrong here, if its not kind of a bug, just forgive me.

Smallest code to reproduce the problem. The crash is caused because SQVM::Execute is not reentrant (due to our suspension code), but the call/acall function can cause it to be re-entered.
