Parrot_api_make_interpreter() cause a crash when another interpreter already exists

[kristaba]

When a second interpreter is created through the API, the function crash with the following backtrace :

src/thread.c:1397: failed assertion '!interpreter_array'
Backtrace - Obtained 32 stack frames (max trace depth is 32).
/usr/local/lib/libparrot.so(+0xc22f2) [0x2db92f2]

/usr/local/lib/libparrot.so(Parrot_api_make_interpreter+0xf6) [0x2db2176]

The only way I find to prevent this is to create a "parent" interpreter and to call Parrot_api_make_interpreter() using this parent to get a new interpreter.

Closing this ticket, as it is a dupe of #1880, which requires a big threading overhaul to change.
