Subject: [PATCH] Fixed iteration limit hit from execproc (#15723)
 [backport:1.2] [backport:1.4]

When calling procs from Nim in Nimscript you could hit the VM iteration limit even though the code is functioning properly. This resolves that by making the iteration limit reset eachtime you call a proc.
