-  # Upper pin: m2crypto 0.46.0 rewrote ssl_read() in src/SWIG/_ssl.i and inverted the
-  # handling of ssl_sleep_with_timeout()'s return value (and dropped the gettimeofday()
-  # that initialises the deadline). Any read() on a connection with a timeout set now
-  # busy-loops and returns with a stale SSLTimeoutError set, which surfaces as
-  # "SystemError: <built-in function ssl_read> returned a result with an exception set"
-  # and breaks all DIRAC DISET/dips connections. Still unfixed upstream as of 0.49.0.
