Packages cannot be loaded in threads (tclkit 8.5.6 and 8.6b1)

[GoogleCodeExporter]

It was a big surprise that my app working with TclKit 8.5.2 is no more
working on TclKit 8.6 (b1).
the following script

 #----------------------------------------
  # load http (or any other package) in main thread
 package require http
  # OK

  # now create a thread and load http in (or any other package)
 package require Thread

 set t0 [thread::create]
 thread::send $t0 {
   package require http
 }
   # OK in 8.5.2
   # KO in 8.6b1.
   # KO in 8.5.6
   #    Error is "can't find package http"
 #----------------------------------------

I noticed that in 8.6b1 thread "auto_path" is not set !
( in 8.5.2 it is correctly set)

Moreover,
in 8.6b1 running
   thread::send $t0 "namespace children ::"
returns
  ::thread ::tsv ::tpool ::oo ::tcl
whilst in 8.5.2 it returns:
  ::thread ::mk ::tsv ::tpool ::mk4vfs ::vfs ::tcl

I also tried to set auto_path in the t0 thread

 thread::send $t0 [list set ::auto_path $::auto_path]
 thread::send $t0 {
   package require http
 }
but result (in 8.6) is always "can't find package http"

** Is it a bug in 8.6 or is there something wrong with my code ?
**  In case of bug, is there a workaround ?

thanks for your help 

** Note:
Currently the official supported version on this site is 8.5.2 (and it works).
I downloaded 8.5.6 and 8.6b1 from Pat Thoyts's site.

The fault here was in the kitgen build and the way that it initialized the tcl
interpreter. So anything built by me using kitgen suffered trouble with this. I 
have
since fixed it and included a test script so each release gets validated for a 
number
of similar problems.
8.5.7 is ok now and 8.5.8 will be ok too.
