[Sbcl-devel] concurrent hash table access inside sbcl

[Attila L. <att...@gm...>]

the current list, new ones on the top:

 - SB-DI::MAKE-COMPILED-DEBUG-FUN accessing *compiled-debug-funs*

 - SB-PCL::GET-SECONDARY-DISPATCH-FUNCTION1
     this one is probably the most serious one, because AFAIU this ht
has high traffic

 - FIND-PACKAGE
    this may also lead to trouble, but the rate of package definitions
is low enough to keep it at the end of the TODO...

  - SB-IMPL::EXTERNAL-FORMATS-FUNS
    this one is safe, the ht is not modified at runtime (so the error
is a false alarm from concurrent reads)

  - SB-ALIEN::ALIEN-TYPE-CLASS-OR-LOSE
    this one is also a constant ht. it's also quite small (16) so it
would probably be faster as a linear search. it needs to be measured,
though.

  - SB-PCL::DEFAULT-CONSTANTP calling SB-C::CONSTANT-SPECIAL-FORM-P
    this is another small read-only ht
