Well, it's only a small C program, and it's likely in cache, not
executed via the shell but directly, so the overhead is pretty minimal
compared to the actual Mail::SpamAssassin scanning itself.

That said, after a little looking around, there's both a libspamc.so
available (without documentation?), and a protocol description in
the SA distribution in spamd/PROTOCOL. So it should be possible to
create a standalone perl version of spamc.

However, I probably won't bother... unless we can show that the overhead
is significant.

Oh, I'm using IPC::Open2 to write to and read from spamc, and prevent
tempfiles and executions via the shell. If you're interested, let me
know.
