"FreeBSD have a very low default file handle limit"?

[Zhang Weiwu]

I am reading the MySQL manual for 4.4.1-alpha where it said:

"FreeBSD is also known to have a very low default file handle limit." 
(Section 2.4.6.1)

I check the limit by using:

 >sh -c ulimit -n 
                                                                                
<
unlimited

Though I don't know if this is the correct way to check "default file 
handle limit", but it looks like FreeBSD does not "have a very low 
default file handle limit"?
