I'd advise adding appropriate UNDERFLOW_EXCEPTION_OK, with comments 
referencing relevant bugs (existing or new), in that case.

I believe I understand the possible causes of spurious underflow in csqrt 
(bug 14157), that on x86/x86_64 only appear for "double", but fixing them 
(for all three implementations) will involve also adding new testcases for 
some spurious underflow cases not currently covered by the testsuite - and 
those cases may require ulps updates for all architectures, so meaning 
they are best avoided during the freeze.

I do not know the causes of spurious underflows from Bessel functions (bug 
14155), but I think that bug could reasonably be considered to cover the 
long double cases as well.
