uploading new js script doesn't kill current running script in RAM. - callbacks not called even if function completes

I'm beginning to suspect that is the esp wroom. It only has 512K RAM.

I changed the code above to do 3 manual manual disconnects and you can see (below) both the disconnect and connect callbacks were called the first time but then not called afterwards (I used a timeout) even though it was really disconnected and connected. Sometimes though when I run it they may get all called for all three trials. The callback failure is not particularly consistent unless I fail to do a hard reset in which case then never get called.

I know that for low.js the minimum requirement is wrover (has extra (ps)ram and flash) maybe that is also true for espruino? @MaBe? Have others had similar issues issues using a wroom??
