I have been doing either console.readline or a flat out sleep--both always get to the same part of the sequence--#625 with the default SyncProcessingLImit. with SyncProcessingLImit set to 10000, it can get to 5125
the number being the variable i in the print
if i pick a higher syncprocessinglimit, it again to a higher i before just getting "stuck"
for your test, can you try with a low syncprocessinglimit? the 10000000 i threw in there makes it very hard to hit it
