Exporter and memory footprint reduction

[Mattia Barbon]

  Hi,
the list of constants and event names available for exporting (stored in 
Wx::Wx_Exp) wastes about 1MB of RAM (measured using heap(1), Snow 
Leopard, 64bit Perl); for a 32bit Perl the amount of wasted memory is 
about 800KB.

  The simplest way to reduce memory occupation is to move the list of 
exported constants to C/XS; this should not increase the compiled code 
size, since the wxPerl so/dll/dylib already contains the constant names.

  In order to do this, I need to change the way constants are exported, 
which in turn means partially or totally replacing Exporter.  This 
change will benefit all wxPerl users, and in particular those using 
threads; do you think it is worth implementing?

Regards,
Mattia
