This makes sure `txsdata` always outlives the Script check queue (since local objects are destructed in reverse order of construction). This is the root cause for a security vulnerability reported by Cory Fields in 2024 that could be exploited by crafting an invalid block to cause nodes to read freed memory. The vulnerability was covertly fixed in commit `492e1f09943fcb6145c21d470299305a19e17d8b`. See security advisory for CVE-2024-52911 for more details.
