cache propagation issue on OSX

[djarecka]

test test_cache_propagation1 doesn't work on OSX, I believe this is a problem that OSX sets tempdir differently:
wf.cache_dir is PosixPath('/var/folders/32/823z586933zbm26chcmcqq1m0000gp/T/tmpzmou1eal')
and t1.cache_dir is
PosixPath('/private/var/folders/32/823z586933zbm26chcmcqq1m0000gp/T/tmpzmou1eal')

Ugh. We had an issue with this in nipype 1, too.

nipy/nipype#2395
nipy/nipype#2639

yes, remember I was debugging this at some point... It's one of the issue that comes back from time to time and it's always annoying...

I think the secret is to release a virus that permanently breaks OSX.

[djarecka]

at some point that might be the only solution..;-) One OS to rule them all!

we could use resolve:

(Pdb) wf.cache_dir
PosixPath('/var/folders/sm/488rz12j279_gyxrq7z971zw0000gp/T/tmpymbiqag1')

(Pdb) wf.cache_dir.resolve()
PosixPath('/private/var/folders/sm/488rz12j279_gyxrq7z971zw0000gp/T/tmpymbiqag1')
(Pdb) t1.cache_dir.resolve()
PosixPath('/private/var/folders/sm/488rz12j279_gyxrq7z971zw0000gp/T/tmpymbiqag1')
(Pdb) t2.cache_dir.resolve()
PosixPath('/private/var/folders/sm/488rz12j279_gyxrq7z971zw0000gp/T/tmpymbiqag1')

this should work for the tests.
