There are some strange LUA functions which do the checking by theirself. InteractUnit("mouseover") is one of them.

Patch or whatever to make sure the write is 0; Fixes CanPerformAction and all inline checks. Wasn't scanned last time I checked, although it might become watched now
Do note that I only tested with /run and macros so I don't know if addons use a different code path.

Doesn't matter, thanks! What you did is you placed a write bp on this global reference and backtraced it to this i guess :P Thanks for that, it's awesome.

Just chekced myself. This value gets referenced several hundred times a second. Pretty weird :P

0083CD32 - A3 F46CD300 - mov [GetBattlenetAllocator+6D57E4],eax
0083CDFB - 89 0D F46CD300  - mov [GetBattlenetAllocator+6D57E4],ecx
0083DB86 - C7 05 F46CD300 00000000 - mov [GetBattlenetAllocator+6D57E4],00000000
0042B1DC - 89 0D F46CD300  - mov [GetBattlenetAllocator+6D57E4],ecx
0042B3E4 - 89 15 F46CD300  - mov [GetBattlenetAllocator+6D57E4],edx
0083DC01 - 89 0D F46CD300  - mov [GetBattlenetAllocator+6D57E4],ecx

Yes that's exactly what I did Logged all the writes that weren't zero just after pressing enter on a /run command (there were only 3) and then tried disabling them one by one.
