GC can be annoying when that happens... For git-svn, perhaps
this can be appropriate to at least allow the import to continue:

diff --git a/perl/Git/SVN.pm b/perl/Git/SVN.pm
index 76b2965905..9b0caa3d47 100644
--- a/perl/Git/SVN.pm
+++ b/perl/Git/SVN.pm
@@ -999,7 +999,7 @@ sub restore_commit_header_env {
 }
 
 sub gc {
-	command_noisy('gc', '--auto');
+	eval { command_noisy('gc', '--auto') };
 };
 
 sub do_git_commit {


But yeah, somebody else who works on git regularly could
probably stop repack from writing thousands of loose
objects (and instead write a self-contained pack with
those objects, instead).  I haven't followed git closely
lately, myself.
