pyfitsleak.py

import objgraph
import pyfits
import gc
import numpy as np

print("Create table")
#a=pyfits.Column(name='',format='K',array=[1,2,3]) # Column instead correctly frees up memory
a=pyfits.new_table([pyfits.Column(name='',format='K',array=[1,2,3])])

print("Delete table")
del a

print("Garbage collect")
gc.collect()
gc.collect()
gc.collect()

print("Still there")
print(objgraph.by_type('recarray')[0])

output:

Create table
Delete table
Garbage collect
Still there
