Hi,

IMHO this approach is suboptimal, since it depends on user's ability to 
debug reason of failure of each particular script. I think since target 
platform allows execution of shared libs by default our emulation layer 
should do the same without requiring user to set some obscure sysctls first.

I have prepared a patch to remove that sysctl and make such behaviour 
default for linux ELF shared libs. Patch can be found here:

http://www.pbxpress.com/~sobomax/linux_et_dynamic.patch

If there are no objections I would like to commit it (also removing 
respective linux.4 delta).

Thanks!

Regards,

Maxim
