Knuth comment in tex.web (section 12) is that hyph_size
should be a prime number (but it is not checked in the code).
I admit I do not now implications (effectiveness of hash function
for locating the hyphenation exception?) not following this constraints.
I'd suggest default setting of hyph_size to a prime that is 
higher than sum of biggest expection lists for at least American 
English and German (current dehyphtex.tex has about 800 words).
A prime around 5000 may suffice for some years.
