Looking at the code, I don't actually understand how you get
inconsistent TMPDIRs, as the name seems to be derived from the master
queue name in the calls of sge_make_tmpdir.

Maybe, though that seems quite obscure and less important than problems
caused by the current implementation, even if I'm now confused how they
arise...

Yes, that's what I mean. I'm inclined to change it anyway if there's no
obvious reason. (The id is only unique in a given cell, and you could
currently have trouble from multiple cells with job ids of similar
sizes, though I doubt that's at all common.)

I'm not sure it helps, but dqs_make_tmpdir:
/* Note could have multiple instantiations of same job, */
/* on same machine, under same queue */
sprintf(str,"%s/%d.%s.%d",qconf->tmpdir,job->job_number,qconf->qname,me.pid);
c.f. sge_make_tmpdir:
/* Note could have multiple instantiations of same job, */
/* on same machine, under same queue */
snprintf(tmpdir, ltmpdir, "%s/"sge_u32"."sge_u32".%s", t, jobid,
jataskid, lGetString(qep, QU_qname));
