is not Gnus fail-safe ?

[Sebastien Kirche]

Hi,

this morning when i started Gnus, it hang on a rss feed that it was not able
to fetch. And then no more Gnus.

Here is the messages i got :

After several attempts i managed to  C-g at "Opening nnrss server..." to let
Gnus finish to initialize.

Is there a mean to make Gnus go on if one or more source fails to deliver ?

I have several mail sources (nnimap, nndoc, nnmh) some nntp and recently few
nnrss that use to work. 

Nnimap or  nntp fail  sometimes but  they seem not  to block  Gnus (actually
nnimap seems to freeze Gnus occasionally).
