[uml-user] threads in x86_64 UML

[Riccardo M. <ric...@gm...>]

Hello,

I'm trying to run some MatLab compiled code in a x86_64 Debian squeeze UML;
unfortunately, the code crashes and the backtrace indicates that the problem is
due to a failing clone() call.

Googling the issue, I found hints that this might be because UML does
not support
NPTL, which is the threading model used by Debian's glibc on x86_64.

So, questions:

1) does UML support NPTL? if not, is this a coming feature?

2) is there any workaround to disable NPTL in glibc/x86_64? (e.g., by
   substituting it with Linuxthreads...)

Thanks for any suggestion!

Riccardo
