Um..., nevermind.  That would probably not be useful.  All that time
elapses between these two calls:

      876  6251810 [main] wish84 3360 path_conv::check:
this->path(g:\home\user\wishrc.tcl), has_acls(0)
 35680785 41932595 [unknown (0xA64)] wish84 3360 _cygtls::remove: wait
0xFFFFFFFF

and since the debug print for the unknown thread is at the beginning of
the _cygtls::remove function, that is not the problem.
