+# we can't really lock based on DSN, as we do not yet have a way to tell that e.g.
+# DBICTEST_MSSQL_DSN=dbi:Sybase:server=192.168.0.11:1433;database=dbtst
+# and
+# DBICTEST_MSSQL_ODBC_DSN=dbi:ODBC:server=192.168.0.11;port=1433;database=dbtst;driver=FreeTDS;tds_version=8.0
+# are the same server
+# hence we lock everything based on sqlt_type or just globally if not available
+# just pretend we are python you know? :)
+
+
+ # when we get a proper DSN resolution sanitize to produce a portable lockfile name
+ # this may look weird and unnecessary, but consider running tests from
+ # windows over a samba share >.>

+
+ # provide locking for physical (non-memory) DSNs, so that tests can
+ # safely run in parallel. While the harness (make -jN test) does set
+ # an envvar, we can not detect when a user invokes prove -jN. Hence
+ # perform the locking at all times, it shouldn't hurt.
+ # the lock fh *should* inherit across forks/subprocesses
+ #
+ # File locking is hard. Really hard. By far the best lock implementation
+ # I've seen is part of the guts of File::Temp. However it is sadly not
+ # reusable. Since I am not aware of folks doing NFS parallel testing,
+ # nor are we known to work on VMS, I am just going to punt this and
+ # use the portable-ish flock() provided by perl itself. If this does
+ # not work for you - patches more than welcome.
