Since it seems nobody looked at the GCC import run (which means to use
the svnimport), I ran it again, under strace control:

... 4279 trunk/gcc/config/i386/xm-sco.h ...

This time it broke at a different revision, so I guess it's not a SVN
or git / git-svnimport problem, but rather a problem of my Perl
installation or the kernel itself?

strace of this:

close(6)                                = 0

What are possible reasons for clone() to fail with -ENOMEN? I have to
admit that the box _is_ loaded a bit all the time:
