Encode lazy-loads encodings on an as-needed basis. This is
great for short-lived programs, but leads to fragmentation in
long-lived daemons where immortal allocations can get
interleaved with short-lived, per-request allocations.
Since we have no idea which encodings will be needed when
there's a constant flow of incoming mail, just preload
everything available at startup.
# fragmentation since common allocators favor a large contiguous heap.
sub preload {
my ($self) = @_;
+
+ # populate caches used by Encode internally, since emails
+ # may show up with any encoding.
+ require Encode;
+ Encode::find_encoding($_) for Encode->encodings(':all');
