[New-bugs-announce] [issue12190] intern filenames in bytecode

[Mike Solomon]

New submission from Mike Solomon <msolo at gmail.com>:

I work on a large app and we noticed that a surprising portion of our heap was filenames embedded the the bytecode.

This one-line patch to intern filenames reduces our on-disk size about ~15% and brings down our heap and in-memory object count by a similar percentage.
