Thanks a lot for this.  The test suite now runs, but I see consistent
fail results on kfreebsd-amd64:

If I invoke ./Tester or ../src/lbzip2 directly from the shell, it works
fine for all the valid test cases, and produces the same output as
minbzcat.  It only fails when invoked by 'make check' (using only -j1).

(To see that. I added +x to the shell invocation of ./Tester and removed
2>/dev/null from the decompressor command lines).

 92870 lbzip2   CALL
mmap(0,0x20001000,0x3<PROT_READ|PROT_WRITE>,0x1002<MAP_ANON|MAP_TYPE|MAP_PRIVATE>,0xffffffff,0)
 92870 lbzip2   RET   mmap -1 errno 12 Cannot allocate memory

 92870 lbzip2   GIO   fd 2 wrote 74 bytes
       "lbzip2: unable to create a POSIX thread: Resource temporarily
unavailable
       "

It is interesting that only some of the .bz2 test cases trigger the
problem, while minbzcat has no problem with them.  I tried changing the
1GB "ulimit -v" in ./Tester to 2GB or 256MB which made no difference.
The system had approx. 5GB free memory anyway.
