So you basically mimicked the makefile rule that this commit removed
into your own test suite.  Reverting the change does not really help,
because we'd be back to square one where there would be problems in
parallel runs for developers.  Saying that, I would not mind adding an
option to pg_regress to control if this cleanup code is triggered or
not, say something like --no-tablespace-cleanup?  Then, you could just
pass down the option by yourself before creating your tablespace path
as you wish.
