Pavel. I have bit 'ol enterprise daemon running with established file
descriptors serving thousands of connections
which periodically require entropy.  Now I run out of descriptors. I
can't establish new connections. but I should
now halt all the other ones that require entropy?  I should raise
SIGKILL on my process serving these thousands
of connetions?  I don't think so.

If that long-running daemon periodically needs something from a device,
one would better keep the fd for that open the whole time. Saves some
CPU cycles and latency too BTW.

Agreed.

On the other hand, keeping a fd open is quite tricky for a
library. But better solution might be to make that easier.

open( , O_IM_A_LIBRARY_GIVE_ME_ONE_OF_THREE_RESERVED_FDS) might be one
solution. Actually, one reserved fd should be enough.
