Hi Pierpaolo,

Yes it does. There's even a routine check in the test suite which does
this (e.g. if you do make check ARGS="-R oddthr", which tests this
feature plus also an odd number of threads).

Another way to do a test run for this feature is as follows. You should
be able to derive info about the necessary command lines from the output.

./linalg/bwc/bwc-trace.sh bindir=$PWD/build/`hostname`/linalg/bwc 
random_matrix_size=800 mn=128 seed=1 thr=2x2 pre_wipe=1 wdir=/tmp/bwc-2seq

which will leave the internal files in /tmp/bwc-2seq.

Note though that the linear generator program is still utter crap, and
that the more sequences you have, the more you'll suffer.
