I bet you're going to run out of file handles.

I'll bet you I won't :-)

$ ulimit -HSn 8192

A file descriptor is really just an entry in a C array which is maintained by the OS. Although by default the size of that array is typically 512, 1024, .... or some other function of base 2 depending on OS etc you can make it virtually anything you want within reason. See this for some more details.

[ambrus]: which is sort of a drawback compared to the ages of typewritten manuscripts representing content only to which the typesetter applies formatting, but that process required much more manual labor.
[ambrus]: If you want to typeset a manuscript, you can still do much less work then in the manual typesetting ages and get good formatting.
[ambrus]: All with only cheap modern computers and software.
[ambrus]: Something you can have at home and your corner print shop, without a whole printing press's worth of equipment.
