The Proposed Question Sandbox on meta.codegolf.stackexchange.com, formed by a merge of 14 questions, currently has 510 answers (don't worry, it's all under control!). I'm worried that if there is a maximum, it might be reached.
I was previously concerned that the number of answers may be stored as an 8-bit integer, and hence the limit would be 256, but this is obviously not the case.
Is there a maximum number of answers to a single question? If not, is this because the databases use an integer type of arbitrary size? If yes, what causes it (the use of 32-bit integers, say)?
