signal 6 in CVS.

[Han-Wen Nienhuys]

I regularly get aborts with current CVS. Call trace:

the crash always comes from

          /* Thread has not been suspended, which should never happen.
           */
          abort ();

I suspect that make_stringbuf() or one of the related functions in the
call stack forgot to set some sort of mutex lock.

Marius, can you investigate?
