Re: Cygwin and filter selection

I can confirm the following report except that the limits of the return
sizes on my system are different. For tr the limit is 33K. As Tim noted,
sort seems to have no limit ... ?

OK. I've found some additional behavior that might shed some more light:

For certain filters ('tr' for instance) the maximum return size on my
system is 16k (0x4000) but for some other filters (custom filters I
wrote) the maximum return size on my system is 17k (0x4400). Even more
interesting, 'sort' doesn't seem to have a problem with any size (I
stopped testing at 2 MB).
