[SQU] file map bits in use

I was checking my cachemgr.cgi and went to see store stats, I got this:

I am concerned about file map bits in use. My storage space is still
pretty empty, but file map bits are at around 90%. What exactly does
that mean? I get nervous when I see stuff above 75%, even if I don't
knwo what it is. thanks,
