Hi Paul,

Good point, I think so.

I did that and pushed it as 549d15712fdc1f58ce0dd11117eb79535ec19f2c.

Let me know if anything is amiss!

Hello!

A colleague of mine noticed that our ‘hdf5’ library wasn’t
thread-safe.  Turns out there’s an option to make it thread-safe (oh!),
it’s turned off by default (oh?!), and when you pass it ‘configure’
invites you to turn off no less than C++, Fortran, and the high-level
interface (d’oh!).

It also tells you that, if you insist, you can go ahead and pass
‘--enable-unsupported’, but you’re on your own.

We found that Debian chose to pass ‘--enable-unsupported’, and indeed
that seems to be saner than providing a variant that does very little,
but does it in a thread-safe way.

Thoughts?

Thanks,
Ludo’.
