Problem with use of memory

Hello :)
 
I'm using libetpan 0.41 in a Mail Program running under Solaris
 
I'm using this code to get new Mail Header from the server.

struct mailimap_set * set;
struct mailimap_fetch_Type * fetchType;
clist * result;
clistcell * current;
int last;
int r;

last = imapstruct->imap_selection_info->sel_exists;
set = mailimap_set_new_interval( 1, last ); /* Index start mit 1!!!! */
fetchType = (struct mailimap_fetch_Type *)mailimap_fetch_type_new_all( );
r = mailimap_fetch( imapstruct, set, fetchType, &result );
mailimap_set_free( set );
mailimap_fetch_type_free( fetchType );

clist_free(result);

But when I execute this code twice, the use of memory gets higher and
higher. It seems that the clist_free function don't return all memory back
to the program for further allocations. 

Can someone tell me, what to do, that it don't use more memory in the second
run, than in the first run? The mails were in both cases the same. The
problem must be in this peace of code, because I've tested the other peaces,
such as login and logout, and it works. When I leve the mailimap_fetch
function out, it don't allocate as much memory, too.

Thanks in advance :)
Daniel
