调研方向
Start by reading the repeat_infinite() implementation and the source types it wraps, then reproduce the reported growth with the Rust 0.20.1 setup: a Sink playing a Decoder over a Cursor<Vec<u8>>. Compare memory use with and without repetition over time. The issue is resolved when repeated playback no longer causes unbounded memory growth; the report does not name a test or file.

描述
Hello,
I'm using Rodio for my application and I'd like for my music to repeat multiple times. I've found the repeat_infinite() function for the Source struct but when I monitored the memory usage I've found out that it's growing about at 10mb every 15 seconds.
I haven't checked if it eventually caps, I only saw that it went from 30mb of memory to 100mb+.
Not using repeat_infinite() works as intended, the memory usage doesn't move.
In my app I create a Sink and I append the Decoder wrapping my music. I assumed that the problem was about buffering more and more music, but in my case the music is in a Cursor<Vec<u8>> so it shouldn't load any more of it (plus my music file is definitely less than 70mb).
