yes, we shall fix it.

very good.

mmm, I thought that uclinux treated the fork->vfork aliasing  
transparently (via #define or something like that...), clearly I was  
wrong :)

So, you can try a couple of solutions:

1) use the iterative server model by setting "model iterative"  
directive in your kloned.conf file, e.g.:

=-=-=-=-=-=-=-=-=-=-=-=
server_list	main

main.model	iterative  <== set this explicitly (otherwise it pre-forks)
main.type	http
main.addr.type	IPv4
main.addr.port	8080
...
=-=-=-=-=-=-=-=-=-=-=-=

2) try out the attached patch which basically does a s/fork/vfork over  
the whole klone source tree (just 3/4 hits).  I haven't tried it on a  
real system (so you are the very first beta tester :)).
Don't forget to append the vfork patch to the KLONE_TARGET_PATCH_FILE  
variable in the top-level Makefile:

=-=-=-=-=-=-=-=-=-=-=-=
KLONE_TARGET_PATCH_FILE = $(CURDIR)/makl.patch
KLONE_TARGET_PATCH_FILE += $(CURDIR)/uclinux-vfork.KLONE_REL_2_0_2.patch
=-=-=-=-=-=-=-=-=-=-=-=

ciao and tell us about your findings and issues !
t.


PS: if the iterative mode fails, use -F (i.e. do not call daemon(3)).
