Hi,

As you may know, pkgin uses libfetch in order to download packages. Since 
5.1 release of NetBSD, many pkgin users are facing weird issues when 
downloading from FTP. These issues only appear when downloading many 
packages.

The first behaviour i've noted myself is that FTP connections will stack 
to the point the FTP server will stop answering. While reading libfetch's 
source code my understanding was it is able to re-use an established 
connection, am i wrong ? Stranger thing is that will occur even if i 
explicitly "close" the connection using fetchIO_close() (which i'm not 
sure what it actually does).

Second behaviour i have noted when _not_ using fetchIO_close() is that the 
first download will go through, but the next connection to a FTP server 
will hang forever.

Latest code for the download part is available here: 
http://pkgin.cvs.sourceforge.net/viewvc/pkgin/pkgin/download.c?revision=1.3&view=markup

The real question behind this mail is: what is the "good way" to use 
libfetch when downloading many items using the same connection ?

Any hint welcome...

Cheers,
