"Cannot import name Popen" in IronPython 2.7.3 -


i'm having weird problem where, though "clr.addreference('ironpython.stdlib')" @ top of ironpython code (i have built copy of stdlib readily findable), unable access popen. multithreaded application, many threads (ten, right now) trying access script @ same time.

i don't have problem accessing ironpython @ console.

2013-09-03 17:10:11.5197 error pythonscriptengineproviderlib.pythonscriptengineprovider.executecompiledcodeinternal not execute python code. ironpython.runtime.exceptions.importexception: cannot import name popen    @ ironpython.runtime.importer.importfrom(codecontext context, object from, string name)    @ microsoft.scripting.interpreter.funccallinstruction`4.run(interpretedframe frame)    @ microsoft.scripting.interpreter.interpreter.run(interpretedframe frame)    @ microsoft.scripting.interpreter.lightlambda.run2[t0,t1,tret](t0 arg0, t1 arg1)    @ ironpython.compiler.pythonscriptcode.runworker(codecontext ctx)    @ ironpython.compiler.runtimescriptcode.invoketarget(scope scope)    @ pythonscriptengineproviderlib.pythonscriptengineprovider.executecompiledcodeinternal(compiledcode cc, idictionary`2 scopevariables) in  ...

although don't have solution (i op), appears it's problem occurs @ process startup. starts working after suitable waiting period. although not sure period is, see subroutines depend on working expected few minutes later (they wait, , reattempt later when experiencing failure).

since long-running process, problem shouldn't have significant cost, now. however, if had guess, seems stdlib may have loading delay may block initiating thread, not others.
