The imapfilter+lua distribution had Lua 5.0.2 + patches that enhanced the
popen() function of Lua and added a pclose() that returned the exit status of
the child process. 

Since imapfilter 1.0-rc3 I implemented my own version of popen(), along with
pclose(), and also added some auxiliary functions that make piping to the stdin
and from the stdout of a process easier.  These functions are pipe_to() and
pipe_from(), which are documented in the imapfilter_config(5) manual page and
used in examples in sample.extend.lua. So, you should use these functions
instead of popen()/pclose()/read()/write()/whatever, demonstrated in previous
release candidates of imapfilter.
