[Boost-build] Errors in windows with multiple parallel jobs

Hello,

I'm using a quad-core machine and using the last bjam from svn trunk (r48043).
And as long as I use -j in bjam I have occasional problems where
a install action tries to copy a file and fails, where the just before
process creates that file. Also when trying to create lib files.
I'm using windows vista x64.
When I don't use -j it works fine.

My boost.build v2 version is of r46411 in trunk.

For example:

msvc.link.dll ..\new_boost\boost_1_36_trunk\bin.v2\libs\thread\build\msvc-9.0\de
bug\address-model-32\debug-store-database\threading-multi\boost_thread-vc90-mt-g
d-1_35.dll
   Creating library ..\new_boost\boost_1_36_trunk\bin.v2\libs\thread\build\msvc-
9.0\debug\address-model-32\debug-store-database\threading-multi\boost_thread-vc9
0-mt-gd-1_35.lib and object ..\new_boost\boost_1_36_trunk\bin.v2\libs\thread\bui
ld\msvc-9.0\debug\address-model-32\debug-store-database\threading-multi\boost_th
read-vc90-mt-gd-1_35.exp
LINK : fatal error LNK1104: cannot open file '..\new_boost\boost_1_36_trunk\bin.
v2\libs\thread\build\msvc-9.0\debug\address-model-32\debug-store-database\thread
ing-multi\boost_thread-vc90-mt-gd-1_35.lib'

I don't really understand what happens, if I retry the build, it
works, or if it fails, it does it
in another point completely which then succeeds when trying again.
