Changes for version 1.01 - 2018-08-14
- attempt to port to strawberry perl, but it has too many broken functions (non-working malloc, overrides setjmp with nonexistant PerlProc_setjmp etc.).
- do not require custom config for pthread on win32.
- usleep on some bsds does not support a time > 1e6, so use sleep+usleep :/
- Coro::Multicore - make coro threads on multiple cores with specially supported modules
