garbage meter in fractional garbage sometimes temporary disappears

[GoogleCodeExporter]

i noticed this long time ago, but now if we want to make fractional garbage 
default it gets higher priority. sometimes fractional garbage meter disappear.

How to observe issue:
1. play 3p game with fractional garbage
2. one player dies
3. if one of remaining player have 0.5 in his garbage queue it should be there 
permanently because you don't cancel <1.0 garbage. but sometimes temporary it's 
not visible (both bar and number).
