This thread got me wondering how many file-handles are open for INNODB tables since it is only one large file on the file system. A quick look at our production server that is running approximately 50 tables within an INNODB instance, I see the number of open file handles is significantly less than 50. Which is what i would have expected. Looking at the other table formats, I do see a file handle open for every single table (more than one file handle since there is multiple files that describe a table under MyISAM).
