Re: [f2py] fortran and python threads

Hi Mark,
The python interpreter lock issues should be resolved by using

   threadsafe

statement in a subroutine signature that you want to run from another 
thread. You can use this statement also in a Fortran subroutine that you 
are wrapping: just put it after f2py directive. For example,

subroutine foo
!f2py threadsafe
...
end subroutine foo

HTH,
Pearu
