the overful environment is caused by exporting all the functions in
'subroutines' and 'subroutines-linux'. as soon as they are called, all
variables generated by them (and not explicitely decklared local, of
cause) are exported as usual.
basically you only need to export a function if you want to call this
function from a subprocess; at least in our setup, this never happens.

The only other way to circumvent this problem would be to to patch the
kernel for increasing the environment size... (when I first saw this, I
remembered the good old DOS-times ;) )
