[Bug libc/6050] New: iconv(1) buffers all of stdin in memory

["skunk at iskunk dot org" <sourceware-bugzilla at sourceware dot org>]

When reading from stdin, glibc's iconv(1) frontend buffers the entire input in 
memory, which makes the program unsuitable for very large inputs.

(This problem does not arise when reading a file directly, presumably because 
the input is mmap()ed in that case.)

$ iconv -f utf8 -t ucs2 <lots-o-gigabytes-utf8.txt >/dev/null
Killed

Confirmed with 2.6.1.
