[Pharo-dev] What did happen with CustomHelp?

No. The limit is supposed to be around 500 Mb on windows or 1 Gb for some specifically compiled VMs. 1 Gb VM may not start on windows, you may need to restart the computer before. To bypass the limit the best way is to use a spur VM honestly. Spur32VMs are limited to around 2.7Gb on Windows.

SmallFloat is like SmallInteger: immediate value encoded in oop, and it is only for 64 bits Spur VM. Boxed is the classical VM Float, two 4-bytes word allocated per Float, and is both for 32 bits VM and Float values not fitting in immediate format (3 bits have been stolen from exponent...).
